In the rate equation R=k[A]a [B]b, a and b as exponents decide the:
Correct answer: C. Order of Reaction
- A. Direction of reaction
- B. Extent of Reaction
- C. Order of Reaction
- D. Temperature of Reaction
Explanation
In the rate equation the power to which the concentration of a specific reagent is raised indicates the order of reaction with respect to that particular reagent only i.e, from the questions a is the order of reaction with respect to reagent A. Sum of a and b will give us the overall order of reaction. Other options are irrelevant.

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.
