Assertion: pH of water increases on increasing temperature.
Reason: `H_(2)O rarr H^(+) + OH^(-)` is an exothermic process.

Options

A. Assertion is not true, but reason is true
B. Both assertion and reason are true, but the reason is not the correct explanation for the
C. Both assertion and reason are false
D. Both assertion and reason are true, and the reason the correct explanation for the assertion

Answer

C

Explanation

`H_(2)O to H^(+) + OH^(-)`
Dissociation of `H_(2)O` is an endothermic reaction.
On increasing temperature, `[H^(+)]` ion concentration increases.
`therefore`pH decreases
