Given :
H2(g) + ½O2(g) \(\text { → }\) H2O(g) + q1
H2(g) + ½O2(g) \(\text { → }\) H2O (l) + q2
The enthalpy of vaporisation of water is equal to
H2(g) + ½O2(g) \(\text { → }\) H2O(g) + q1
H2(g) + ½O2(g) \(\text { → }\) H2O (l) + q2
The enthalpy of vaporisation of water is equal to
- q1 + q2
- q1 – q2
- q2 – q1
- q1q2
Answer
(C) q 2 – q 1
