The amount of heat evolved when 0.50 mole of HCl is mixed with 0.30 mole of NaOH solution is

A

58.6 Kcal

B

84.9 Kcal

C

80.7 Kcal

D

68.3 Kcal

Text Solution

Verified by Experts

1 mole of `HNO_(3)` and 1 mole gives heat = 57.0 kJ
In this case `HNO_(3)` limiting reagent and 0.3 mole of `HNO_(3)` and 0.3 mole of NaOH give heat `= 57xx0.3=17.1 kJ`
