Many endothermic reactions that are not spontaneous at room temperature become spontaneous at high temperture.
`DeltaH^(@)` of the endothermic reaction may increases with increase in temperature.

Options

A. If both (A) and (R ) are correct, and (R ) is the correct explanation for (A).
B. If the both (A) and (R ) are correct, but(R ) is not a correct explanation for (A).
C. If (A) is correct, but (R ) is incorrect.
D. If (A) is incorrect, but (R ) is correct.

Explanation

On increasing temperature, the endothermic reaction becomes spontaneous and entropy also increases.
