When the heat shifts the direction of the reaction there has been a change in concentration and equilibrium will then be affected?
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.
Which way will equilibrium reaction shift if keg is large or small?
If the equilibrium constant (K_eq) is large, it means the products are favored at equilibrium. The reaction will shift toward the products to establish equilibrium. If K_eq is small, it means the reactants are favored at equilibrium. The reaction will shift toward the reactants to establish equilibrium.
What happens to the equilibrium if the pressure is increased?
equilibrium will shift to the side of the equation with the least moles in attempt to reduce pressure in the haber process N2+3H2 <--> 2NH3 an increase in pressure causes equilibrium to shift the right because it has the least moles (2 instead of 4) <--> represents a reversible reaction sign
Effects of temperature and pressure on exothermic and endothermic reaction?
An increase in temperature favours an endothermic reaction over an exothermic one as an endothermic reaction takes in the energy from the higher temperature more easily than the exothermic reaction gives out even more energy to the surroundings. Therefore an increase in temperature increases the level of completion and viability of an endothermic reaction, and the opposite for an exothermic reaction. An increase in pressure favours any reaction that forms fewer molecules from more molecules. It does not necessarily favour an exothermic or an endothermic reaction as it depends on the number of molecules on either side of the reaction. An endothermic reaction involves the breaking of bonds to a greater extent than an exothermic reaction, so an increase in pressure would, in a lot of cases, favour the exothermic reaction more than the endothermic reaction.
What happens of the equilibrium of a weak acid dissociation reaction were upset?
The reaction would shift to balance the change
What piece of information will tell you which way the equilibrium of a reaction will shift due to a change in temperature?
The sign of the enthalpy change (∆H) of the reaction will indicate the direction in which the equilibrium will shift with a change in temperature. If ∆H is negative (exothermic reaction), an increase in temperature will shift the equilibrium towards the reactants; if ∆H is positive (endothermic reaction), an increase in temperature will shift the equilibrium towards the products.

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.
How does temperature affect the Keq of a reaction?
Changing the temperature will change Keq. (apex.)
Which way will equilibrium reaction shift if keg is large or small?
If the equilibrium constant (K_eq) is large, it means the products are favored at equilibrium. The reaction will shift toward the products to establish equilibrium. If K_eq is small, it means the reactants are favored at equilibrium. The reaction will shift toward the reactants to establish equilibrium.
If the reaction gets hot is it an endothermic or an exothermic reaction?
The reverse reaction is not always endothermic or exothermic, the reverse reaction is the opposite of whatever the initial reaction is, so if the reaction is endothermic, the reverse reaction is exothermic and vise versa.
If the temperature of a reaction increases what happens to the value of the equilibruim constant?
If the temperature of a reaction increases, the value of the equilibrium constant can either increase or decrease depending on whether the reaction is endothermic or exothermic. For an endothermic reaction, the equilibrium constant will increase with temperature, while for an exothermic reaction, the equilibrium constant will decrease with temperature.
What effect does the removal of heat have on the equilibrium position?
If heat is removed from a system at equilibrium, the system will shift in the direction of the endothermic reaction to counteract the decrease in temperature. This will result in the equilibrium position shifting towards the side of the reaction that absorbs heat.
What would happen if the equilibrium of a weak dissociation reaction were upset?
The reaction would shift to balance the change
How will increasing the temperature affect the equilibrium?
Increasing the temperature of a system at equilibrium will shift the equilibrium position in the endothermic direction to absorb the added heat. This change will favor the reaction that absorbs heat and produces more heat to counteract the temperature increase. Similarly, decreasing the temperature will favor the exothermic direction to produce more heat to counteract the temperature decrease.
What happens to the equilibrium if the pressure is increased?
equilibrium will shift to the side of the equation with the least moles in attempt to reduce pressure in the haber process N2+3H2 <--> 2NH3 an increase in pressure causes equilibrium to shift the right because it has the least moles (2 instead of 4) <--> represents a reversible reaction sign

What is used to describe the conditions of a reaction to equilibrium?
An equilibrium constant
