Teaching RPSC School Lecturer Mock Test Series 2024 Chemistry Thermodynamics First Law Of Thermodynamics And Hess law
Based on the following thermochemical equation
1. H2O(g) + C(s) → CO(g) + H2(g); ΔH = 131 kJ
2. CO(g) + \(\frac{1}{2}\)O2(g) → CO2(g); ΔH = –282 kJ
3. H2(g) + \(\frac{1}{2}\)O2(g) → H2O(g); ΔH = –242 kJ
4. C(s) + O2(g) → CO2(g); ΔH = x kJ
the value of X will be:
1
–393 kJ
2
–655 kJ
3
+393 kJ
4
+655 kJ
