The following results have been obtained during the kinetic studies of the reaction P+Q→S           The correct option for the rate equation for above reaction is

On comparing experimental results of I and II , we can conclude that Rate α P ( when [P] is made 4 times rate became 4 times)On comparing experimental results of II and III , we can conclude that Rate α Q2 ( when [Q] is made 2 times rate became 4 times)Based on above observations, Rate=K[P]1[Q]2
