"Specific Rate" constant changes its value with?
Correct answer: B. Change in Temperature
- A. Time Constant
- B. Change in Temperature
- C. Change in Concentration
- D. Change in Pressure
Explanation
OPTION A: Specific Rate constant is independent of the time constant.OPTION B: According to Arrhenius's equation k = Ae -Ea/T ( k ∝ 1/Ea, k ∝ T) k depends upon temperature. (k has a fixed value for a reaction under given conditions of temperature). A specific rate constant changes its value with a temperature change.Hence, B is the correct option. OPTION C: Specific Rate constant is independent of concentration.OPTION D: Specific Rate constant is independent of pressure.

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.
