Q. No.Three thermochemical equations are given below:
Based on the above equations, find out which one of the relationships given below is correct :
| (i) | C(graphite) + O2(g) \(\rightarrow\) CO2(g); \(\Delta_{r}\)H° = x kJ mol–1 |
| (ii) | Cgraphite + 1/2 O2(g) \(\rightarrow\) CO(g); \(\Delta_{r}\)H° = y kJ mol–1 |
| (iii) | CO(g) + 1/2 O2(g) \(\rightarrow\) CO2(g); \(\Delta_{r}\)H° = z kJ mol–1 |
Based on the above equations, find out which one of the relationships given below is correct :
| 1. | z = x + y | 2. | x = y + z |
| 3. | y = 2z – x | 4. | x = y – z |
