Given that,at 25°C, C(s)+ O₂(g)→ CO₂(g) ΔG° = −394.4 kJ C(s)+ $\frac{1}{2}$ O₂(g)→ CO(g) ΔG° = −137.2 kJ Calculate ΔG° for the reaction below. CO(g)+ $\frac{1}{2}$ O₂(g)→ CO₂(g)

Question

Quizplus · Accepted Answer

To find ΔG° for the given reaction, subtract the ΔG° of the second reaction from the first. This gives: −394.4 kJ - (−137.2 kJ) = −257.2 kJ.

Given That,at 25°C, C(s)+ O2(g)→ CO2(g) ΔG° = −394 12\frac{1}{2}21​ O2(g)→ CO(g) ΔG° = −137

Given That,at 25°C, C(s)+ O₂(g)→ CO₂(g)
ΔG° = −394 $\frac{1}{2}$ O₂(g)→ CO(g)
ΔG° = −137
