The rate constant of a reaction is given by k=2.1xx10^(10)" exp "(-2700/RT) It means that

Answer»

log k vs. `1//T` will be a straight line with slope
`=-(2700)/(2.303" R")`
log k vs. `1//T` will be a straight line with intercept on log k axis `=2.1xx10^(10)`
The number of effective collisions are `2.1xx10^(10)" cm"^(-3)" sec"^(-1)`
Half life of the reaction INCREASES with increase of temperature.

Solution :is wrong because frequency factor gives total number of collicions and not effective collisions `cm^-3 sec^-1`.
(d) is wrng because half - life of the reactions decreases with incerease of temperature ( as reaction BECOMES FASTER ).
