What are 4 things can increase reaction rate?
Increasing temperature, increasing concentration of reactants, using a catalyst, and increasing the surface area of the reactants can all increase reaction rate by providing more energy for collisions between reactant molecules.
What are things that decrease a reaction rate?
Some factors are: low temperature, low pressure, low concentration of reactants, no stirring, coarse particles, etc.
What would happen to the rate of a reaction with rate law rate kno2h3 if the concentration of no were doubled?
If the concentration of NO was doubled in the rate law rate = k[NO]2[H3], the rate of the reaction would increase by a factor of 4. This is because the rate of a reaction typically increases with an increase in the concentration of reactants, raised to a power dictated by their respective coefficients in the rate law equation.
What would happen to the rate of a reaction with rate law rate kNO2H2 if the concentration of NO were double?
The rate would quadruple (increase by a factor of 4). This is because the rate depends on the SQUARE of the concentration of NO.
Can rate of reaction be negative?
No, the rate of a reaction cannot be negative. Rate of reaction is defined as how the concentration of a reactant or product changes over time. It is always a positive value or zero, indicating the direction and speed of the reaction progress.
The decomposition reaction of ammonia gas on platinum surface has a rate constant k equals 2.510-4 mol l-1s-1 what is the order of the reaction?
The rate constant is not indicative of the order of the reaction. To determine the order of the reaction, experimental data (such as concentration vs. rate data) is needed. The order of the reaction can be found by examining how changes in reactant concentrations affect the rate of the reaction.
What factor does affect the most rate of reaction?
The concentration of reactants is the factor that most significantly affects the rate of reaction. Increasing the concentration of reactants typically leads to more frequent and successful collisions between particles, resulting in a higher reaction rate.
What are 4 things can increase reaction rate?
Increasing temperature, increasing concentration of reactants, using a catalyst, and increasing the surface area of the reactants can all increase reaction rate by providing more energy for collisions between reactant molecules.

What statements about activation energy is correct?
Activation energy is the minimum amount of energy required for a chemical reaction to occur. An increase in activation energy leads to a decrease in reaction rate. Catalysts lower the activation energy required for a reaction to proceed, increasing the reaction rate. Activation energy does not affect the overall energy change of a reaction, only the speed at which it occurs.
What is the overall reaction order for this rate law rate equals kA2BC?
The overall reaction order for the rate law rate = k[A]^2[B][C] is 4, which is calculated by summing the individual reaction orders for each reactant ([A]^2 has an order of 2, [B] has an order of 1, [C] has an order of 1).
What 4 things affect a plant?
depends
What would happen to the rate of a reaction with rate law kNO2H2 if the concentration of NO were doubled?
The rate would be four times larger
What are the four factors that affect the rate of a chemical reaction?
The four factors that affect the rate of a chemical reaction are the concentration of reactants, temperature, presence of a catalyst, and surface area of reactants (for reactions involving solids or liquids). These factors influence how frequently and effectively particles collide to form products.
What would happen to the rate of a reaction with rate law rate kNO2H2 if the concentration of NO were double?
The rate would quadruple (increase by a factor of 4). This is because the rate depends on the SQUARE of the concentration of NO.
4 factors that affect blood pressure?
There are four factors that affect the blood pressure. The things that can affect blood pressure are stress, genetics, a high salt intake, and exercise.
What 4 factors increase a reaction rate?
Increase in temperature: Higher temperature provides molecules with more kinetic energy, increasing the frequency of collisions between reactant particles. Higher concentration of reactants: More reactant molecules present in a given volume increases the likelihood of collision. Catalysts: Catalysts provide an alternative reaction pathway with lower activation energy, speeding up the reaction. Increased surface area: Finely dividing or dispersing reactants exposes more surface area, facilitating more collisions and increasing the reaction rate.
