If CH(2)COOH+OH^(-)rarrCH(3)COO^(-)+H(2)...

If `CH_(2)COOH+OH^(-)rarrCH_(3)COO^(-)+H_(2)O+q_(1)`
`H^(+)+OH^(-)rarrH_(2)O+q_(2)`
then the enthalpy change for the equal to

A

`(q_(1)+q_(2))`

B

`(q_(1)-q_(2))`

C

`(q_(2)-q_(1))`

D

`-(q_(1)+q_(2))`

Text Solution

Verified by Experts

The correct Answer is:
C
Eqn. (ii) is for heat of neutralization of strong acid with strong base. Eqn. (i) for weak acid with strong base. The difference `q_(2)-q_(1)` is heat of dissociation of weak acid.
