The absolute enthalpy of neutralization ...

The absolute enthalpy of neutralization of the reaction,
`MgO(s)+2HCl(aq.)+H_(2)O(l)` will be

A

`-57.33` kJ `mol^(-1)`

B

greater than -57.33 kJ `mol^(-1)`

C

less than -57.33 kJ `mol^(-1)`

D

57.33 kJ `mol^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C

Since MgO is an oxide of a weak base, hence its neutralisation will evolve the heat less than 57.33 kJ `mol^(-1)`
