The 503 cm3 reactor was purged of air and methanol vapor was introduced until the pressure was 5.01 kPa. Then the inside ampoule containing 68.6 mg of nitrosyl chloride, NOCl was broken. After equilibrium was established, the partial pressure of NOCl was found to be 2.76 kPa. The test temperature was 50.00 ° C. Find the reaction Δ_rG^o: CH3ONO (g) + HCl (g) → CH3OH (g) + NOCl (g), at the test temperature.
