Answer» Correct Answer - d From `1^(st)` and `2^(nd)` sets of data- no change in rate with the change in concentration of C . So the order with respect to C is zero. From `1^(st)` and `4^(th)` sets of data Dividing eq. (4) by eq. (1) `(1.25 xx 10^(-3))/(5.0 xx 10^(-3)) = [(0.005)/(0.010)]^(x)` or `0.25 = (0.5)^(x)` or `(0.5)^(2) = (0.5)^(x)` `therefore x = 2` The order with respect to A is 2 . From the `1^(st)` and `3^(rd)` sets of data Dividing eq. (1) by eq. (3) `(5.0 xx 10^(-3))/(1.0 xx 10^(-2)) = [(0.005)/(0.010)]^(y)` or `(0.5)^(1) = (0.5)^(y) implies y = 1` The order with respect to B is 1 So the order with respective the reactants A , B and C is 2, 1 and 0. |
