`50.0 mL` of 0.10 M HCl is mixed with `50.0 mL` of 0.10 M NaOH. The solution's temperature rises by `3.0^(@)C`. Calculate the enthalpy of neutralization per mole of HCl. (Assuming density of sol. `=1 g//ml` & specifice heat of water)

A

`-2.5xx10^(2)kJ//"mole"`

B

`-1.3xx10^(2)kJ//"mole"`

C

`-8.4xx10^(1)kJ//"mole"`

D

`-6.3xx10^(1)kJ//"mole"`

Text Solution

Verified by Experts

The correct Answer is:
A
`Q=m S Delta T , rArr (Q_(R))/(2)=(m)/(2)S Delta AT, rArr` So, `Delta T_(1)=Delta T_(2)`
