Following are two first order reactions with their half times given at 25^(@)C A overset(t_(1//2) = 30 "min")(to) Products B overset(t_(1//2) = 40 "min") (to)Products The temperature coefficients of their reaction rates 3 and 2 , respectively , between 25^(@)C and 35^(@)C . if the above two reactions are carried out taking 0.4M of each reactant but at different temperatures 25^(@)C for the first reaction and 35^(@)C for the second reaction , find the ratio of the concentration of A and B after an hour |

Answer» 0.4 M of `B overset(20 "min")(to) 0.2M overset(20 "min") (to) 0.1 M overset(20 "min")(to) 0.05` (for B) `"("(-d[B])/(dt)` will be DOUBLED and hence `t_(1//2)` will be halved) `THEREFORE ([A])/([B]) = 2` |
