Question

For the reaction A + B → product, rate of reaction is 3.6 × 1 0 − 2 mol dm − 3 sec − 1 . When [ A ] = 0.2 mol dm − 3 and [ B ] = 0.1 mol dm − 3 , find rate constant of reaction if it is second order with respective to both reactants.

Rate law is. ​ r = K [ A ] 2 [ B ] 2 3.6 × 1 0 − 2 = k ( 0.2 ) 2 ( 0.1 ) 2 K = 0.04 × 0.01 3.6 × 1 0 − 2 ​ K = 90 mol − 3 dm 9 sec − 1 ​
