For the reaction, A(g) -> products:When the concentration of A(g) doubles, the rate of reaction increases four folds, which means it is:
Correct answer: D. Second order reaction
- A. Negative order reaction
- B. First order reaction
- C. Zero order reaction
- D. Second order reaction
Explanation
In second-order reactions, the rate of reaction is directly proportional to the square of the concentration of the concerned reactant. In this scenario, when we doubled the concentration of A, the rate increases four folds implying 'A' to be of the second order.

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.
