What is Chemical Kinetics?

Back

Chemical Kinetics is the branch of chemistry that studies the rates of chemical reactions and the factors affecting them.

Front

What factors affect the rate of a chemical reaction?

Back

Factors that affect the rate of a chemical reaction include concentration, temperature, surface area, and the presence of a catalyst.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs energy from its surroundings, usually in the form of heat.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases energy to its surroundings, usually in the form of heat.

Front

How does increasing temperature affect reaction rates?

Back

Increasing temperature generally increases the rate of a reaction because it provides more energy to the reactants, leading to more frequent and effective collisions.

Front

How does increasing concentration affect reaction rates?

Back

Increasing the concentration of reactants typically increases the rate of reaction because it leads to a higher frequency of collisions between reactant molecules.

Front

What is the role of a catalyst in a chemical reaction?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. It lowers the activation energy required for the reaction.

Front

What is the rate of a reaction?

Back

The rate of a reaction is the change in concentration of a reactant or product per unit time.

Front

What is a second order reaction?

Back

A second order reaction is a reaction whose rate is proportional to the square of the concentration of one reactant or the product of the concentrations of two reactants.

Front

What type of plot shows a linear relationship for a second order reaction?

Back

The plot of 1/[A] vs time shows a linear relationship for a second order reaction.
