In the rate equation R=k[A]a [B]b, a and b as exponents decide:
Correct answer: C. Order of reaction
- A. Direction of reaction
- B. Extent of reaction
- C. Order of reaction
- D. Temperature of reaction
Explanation
Option C "Order of Reaction " is the correct answer. Order of reaction may be defined as the number of molecules or reactants participating in rate determining step , in R=k[A]a[B]b , the exponent a is the order of reaction w.r.t specie A and b is the exponent of the order of reaction w.r.t specie B, the sum a+b is the overall order of reaction or simply order of reaction.

About Order of Reaction
Reaction order shows how the rate depends on the concentration of each reactant, as expressed in the rate law. Coverage includes zero, first and second-order reactions, integrated rate equations, half-life, units of rate constants and the distinction between overall order and molecularity.
