Given:
- C(graphite) + O2(g) → CO2(g);
ΔrH° = x kJ mol-1
- C(graphite) \(+\frac{1}{2} \sigma_{2}(g) \rightarrow \cot (g)\);
ΔrH° = y kJ mol-1
- \(\operatorname{co}(g)+\frac{1}{2} \mathrm{O}_{2}(g) \rightarrow \mathrm{CO}_{2}(g)\);
ΔrH° = z kJ mol-1
Based on the above thermochemical equations, find out which one of the following algebraic relationship is correct?
- z = x + y
- x = y - z
- x = y + z
- y = 2z - x
Answer
(C) x = y + z
