Question
The heats of the following reactions at 25°C are:
Na(s) + 1/2Cl,(g) → NaCl(s)
AH° = - 98230 cal
H2(g) + S(s) + 2O2(g) → H2SO,(1)
AH° = - 193910 cal
2Na(s) + S(s) + 202(g) → Na,SO,(s)
AH° = - 330500 cal
1/2H2(g) + 1/2CI²(g) → HC1(g)
AH° = - 22060 cal
From this data find the heat of reaction at constant volume at 25°C for the
process:
2NaCl(s) + H,S0;(1) → Na,SO4(s) + 2HCI(g)
