The half-life for first order reaction is independent of initial:
Correct answer: C. Concentration
- A. Temperature
- B. Pressure
- C. Concentration
- D. All of these
Explanation
The half-life of a first-order reaction is independent of the initial concentration of the reactant. The half-life of a first-order reaction only depends on the rate constant of the reaction.

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.
