Given: (i) C(graphite) + O 2 (g) → CO 2 (g); Δ rH – = xkJ mol –1
(ii) C(graphite) + 
O 2 (g) → CO 2 (g); Δ rH – = ykJ mol –1 (iii) CO(g) + 
O 2 (g) → CO 2 (g); Δ rH
– = zkJ mol –1
Based on the above thermochemical equations, find out which one of the following algebraic relationship is correct?
Text Solution
Verified by ExpertsThe correct answer is:
C
Bonus can be claimed because question is incorrect due to misprint in second reaction ie CO 2 in palce of CO(g).
