Two gases A and B are filled in a container. The experimental rate law for the reaction between them, has been found to be Rate =k [A]^2[B]Predict the effect on the rate of the reaction when pressure is doubled :

Answer»

the RATE is doubled
the rate becomes four TIMES
the rate beomces six times
the rate becomes eight times

Solution :When pressure is doubled, CONCENTRATIONS are also doubled.
`Rate_1=k(P_A)^2(P_B)`
`Rate_2=k(2P_A)(2P_B)`
`:. (Rate_2)/(Rate_2)= (k(2P_A)^2(2P_B))/(k(P_A)^2(P_B))`
`=(2)^2xx 2= 8`
