Answer» Correct Answer - (a) Rate of formation of C= 0.076 `Ms^(-1)` ( b) Rate of consumption of B= 0.038 `Ms^(-1)` ( c) Rate of reaction = 0 .038 `Ms^(-1)` Given : `2A + B to 2C` Rate of disappearance of A= 0.076 `Ms^(-1)` (a) Rate of formation of C= ? ( b) Rate of consumption of B = ? (c ) Rate of reaction = ? Rate of disappearance of `A = (d[A])/(dt) = 0.076 Ms^(-1)` (a) Rate of formation of `C= (d[C ])/(dt) = (d[A])/(dt)` `=0.076 Ms^(-1)` ( b) Rate disappearance of `B= (d[B])/(dt) = - (1)/(2) (d[A])/(dt)` `= (1)/(2) xx 0.076 =0. 038 Ms^(-1)` ( c) Rate of reaction `=- (1)/(2) .(d[A])/(dt) = (-d[B])/(dt) = (1)/(2) (d[C])/(dt)` `= (1)/(2) (0.076) = 0.038 = (1)/(2) xx 0.076` `= 0.038 Ms^(-1)` |
