Question

Consider the following single step reaction in gas phase at constant temperature. 2A + B → C The initial rate of the reaction is recorded as r when the reaction starts with 1.5 atm pressure of A and 0.7 atm pressure of B. After some time, the rate r is recorded when the pressure of C becomes 0.5 atm. The ratio r : r is ________ × 10 . (Nearest integer) (A) 7 : 2 (B) 31.5
