The enthalpy of neutraliztion of weak ba...

The enthalpy of neutraliztion of weak base A OH and a strong base BOH by HCl are -12250 cal/mol and -13000 cal/mol respectively . When one mole of HCl is added to a solution containting 1 mole of A OH and 1 mole of BOH , the enthalpy change was -12500 cal/mol . In what ratio is the acid distribution between A OH and BOH?

A

`2:1`

B

`2:3`

C

`1:2`

D

`3:2`

Text Solution

Verified by Experts

The correct Answer is:
A
`750x = 500 rArr x = 2//3` and `y = 1//3` So, `(x)/(y) = (2)/(1)`
