The rate of reaction for a reaction is 30 mol dm-3 sec-1. If the product of concentration of reactant is unity the specific rate constant is:
Correct answer: C. 30
- A. 2.5
- B. 15
- C. 30
- D. 35
Explanation
The specific rate constant is the rate of reaction when the concentration of each of the reactants is unity. In this case, the rate of reaction is 30 mol dm-3 sec-1, and the product of the concentrations of the reactants is unity. Therefore, the specific rate constant is 30 mol dm-3 sec-1. So, the answer is 30.

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.
