The enthalpies of two reactions are `DeltaH_(1)`and `DeltaH_(2)` both positive with `DeltaH_(2)gt DeltaH_(1)`. If the temperature of reacting system is increased from `T_(1)` to `T_(2)` predict which of the following alternative is correct ?

A

`(k_(1))/(k_(1'))=(k_(2))/(k_(2'))`

B

`(k_(1))/(k_(1'))gt(k_(2))/(k_(2'))`

C

`(k_(1))/(k_(2'))lt(k_(2))/(k_(1'))`

D

`(k_(1))/(k_(1'))lt(k_(2))/(k_(2'))`

Text Solution

Verified by Experts

The correct Answer is:
D

As the temperature of reacting system is increased the equilibrium constant of reaction is also increased for endothermic reactions so for two reactions on increasing the temperature by equal amounts .
`(k_(1))/(k_(1))lt(k_(2))/(k_(2))`
