`K_(c)` for the reaction, `A+BhArrP+Q` is `2.0xx10^(-2)` at `25^(@)C` and it is `2.0xx10^(-1)` at `50^(@)C`. Predict whether the forward reaction is exothermic or endothermic.

Text Solution

Verified by Experts

Since,`2.303 log(K_(2))/(K_(1))=(Delta H)/(R )([T_(2)-T_(1))/(T_(1)T_(2)])`
`K` increase with temperature and thus `Delta H` should be positive and thus the reaction is endothermic.
