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? Here k is equilibrium constant at `T_(1) and k'` is equilibrium constant at `T_(2).`

A

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

B

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

C

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

D

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