Yes, a change in temperature can shift the equilibrium of a reaction by changing the concentrations of reactants and products. The direction of the shift depends on whether the reaction is endothermic or exothermic. An increase in temperature will favor the endothermic reaction, while a decrease will favor the exothermic reaction.

What can you calculate if you know the concentration of a reaction's products and reactants as well as the coefficients of each in the balanced equation?
You can calculate the equilibrium constant (Kc) of the reaction. This constant gives you information about the extent of the reaction at equilibrium and helps predict the direction in which a reaction will proceed.
What equilibrium concentrations are affected by changing the initial concentration?
Yes, the concentrations are constant but not necessarily static. The 'forward' reaction rate matches the 'reverse' reaction rate.
The keq of a reaction is 4 times 10 to the -7th at equilibrium the?
This equilibrium constant (Keq) value indicates that the reaction strongly favors reactants at equilibrium. The concentration of products is much smaller compared to reactants. This suggests that the reaction is proceeding in the reverse direction, towards the reactants, at equilibrium.
What happens when there is a very high k value in an equilibrium reaction?
A high k value indicates that the equilibrium strongly favors the products over the reactants. This means that the reaction will proceed toward the products to a greater extent and reach equilibrium faster. A very high k value suggests that the reaction is almost complete in the forward direction.
When a reaction is at equilibrium increasing the temperature favors the reaction that what?
First read this to understand equilibrium: if the point of equilibrium moves to the left there will be more reactants than products. If the point of equilibrium moves to the right there will be more products than reactants. Le Chatelier's principle states that whatever you do to the reaction, the reaction will try and reverse the effects. Eg: heat it, and it will try and cool it down. ANSWER: If you increase the concentration of the reactants (left side), according to Le Chatelier's principle the reaction will try and get rid of the extra reactants, so it will decrease the concentration of reactants. This means the position of equilibrium will move to the right, so more products will be formed.
How would the equilibrium concentration of H2O be affected by adding a catalyst to the mixture?
Adding a catalyst to the mixture would not affect the equilibrium concentration of H2O. A catalyst speeds up the rate of the forward and reverse reactions equally, without changing the position of the equilibrium. This means that the equilibrium concentration of H2O would not be affected by the presence of a catalyst.

Yes, the concentrations are constant but not necessarily static. The 'forward' reaction rate matches the 'reverse' reaction rate.
What is meant by a stress on a reaction at equilibrium?
A stress on a reaction at equilibrium refers to any change that disturbs the balance between reactants and products. This can include changes in temperature, pressure, or concentration. When a stress is applied, the reaction will shift in a direction that helps to relieve the stress and re-establish equilibrium.
The keq of a reaction is 4 times 10 to the -7th at equilibrium the?
This equilibrium constant (Keq) value indicates that the reaction strongly favors reactants at equilibrium. The concentration of products is much smaller compared to reactants. This suggests that the reaction is proceeding in the reverse direction, towards the reactants, at equilibrium.
What correctly describes any chemical reaction that has reached equilibrium?
At equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. The concentrations of reactants and products remain constant, although they are still reacting. The equilibrium position can be affected by changes in temperature, pressure, or concentration.
Why does changing the concentration of reactant shift the equilibrium?
Changing the concentration of a reactant shifts the equilibrium because Le Chatelier's principle states that a system at equilibrium will respond to any external change in order to minimize the effect of that change. If you increase the concentration of a reactant, the system will shift towards the product side to reduce that increase, and vice versa.
What of the following characterizes reaction at equilibrium?
At equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction, resulting in a constant concentration of reactants and products. The system is in a state of balance, where the concentrations of reactants and products remain constant over time.
When a reaction is at equilibrium increasing the temperature favors the reaction that what?

In a reversible reaction two substances are in equilibrium if the concentration of each is doubled but the equilibrium constant remains unaffected?
TRUE
What happens to the equilibrium concentration of reactants when the volume of the reaction system is decreased and why?
When the volume of the reaction system is decreased, the equilibrium will shift towards the side of the reaction with fewer moles of gas to relieve the pressure. This causes the concentration of reactants to increase in order to establish a new equilibrium.
Two factors that determine fate of a chemical reaction in a living cell?
Enzymes play a key role in determining the fate of a chemical reaction in a living cell by catalyzing and regulating the speed of the reaction. Additionally, the intracellular concentration of reactants and products can also affect the direction and equilibrium of the reaction within the cell.
