Rate of first order reaction depends on:
Correct answer: A. Concentration of one reactant
- A. Concentration of one reactant
- B. Concentration of two reactants
- C. Concentration of three reactants
- D. Independence of the initial concentration
Explanation
In a first-order reaction, the rate depends on the concentration of one reactant. This means that the rate of the reaction is directly proportional to the concentration of that particular reactant. The rate law for a first-order reaction is typically written as Rate = k[A], where [A] represents the concentration of the reactant 'A.' So, this option is correct.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
