Stoichiometry
Heat of neutralisation of a strong acid and strong base is always a constant value, i.e., 57 KJ/Kg mole. This is because

The salt formed does not hydrolyse
The strong base and strong acid reacts in aqueous solution
Only OH⁻ and H⁺ ions react in every case
The strong base and strong acid reacts completely

Stoichiometry
Pick out the wrong unit conversion of heat transfer co-efficient.

1 kcal/m².hr.°K = 1.163 W/m².°C
1 W/m² . °C = 0.1761 BTU/ft².hr.°F
1 BTU/ft².hr.°F = 4.88 kcal/m².hr.°C = 20.44 kJ/m².hr°C = 5.678 W/m².°C
1 kcal/m².hr.°C = 0.2048 BTU/ft².hr. °F. = 1.163 W/m².°K
