NEET Chemistry Chemical Kinetics Questions Solved

BOARD

A reaction is of second order with respect to a reactant. How is its rate affected if the concentration of the reactant is (i) doubled  (ii) reduced to half?

As Formula, r = K[R]2

(i) R' = 2R       r = K[2R]2 = 4KR2

 Rate becomes 4 times than original rate

(ii) R' =12R     r = KR22 = K4R2

 Rate becomes 14 times of the original rate
