Carbonyl fluoride (COF2\text{COF}_2COF2) is a gas used in chemical synthesis.
Carbonyl fluoride is formed when carbon monoxide reacts with fluorine:
CO(g)+F2(g)⇌COF2(g)ΔH=−539 kJ/mol \text{CO}(\text{g}) + \text{F}_2(\text{g}) \rightleftharpoons \text{COF}_2(\text{g}) \quad \Delta H = -539\text{ kJ/mol} CO(g)+F2(g)⇌COF2(g)ΔH=−539 kJ/molIf a high temperature is used, only a small amount of carbonyl fluoride is formed. Suggest why only a small amount of carbonyl fluoride is formed at high temperatures.
Predict how the yield of carbonyl fluoride will change if the reaction is carried out at a higher pressure. Give a reason for your answer. [Assume the reaction reaches a position of equilibrium]
Carbonyl fluoride reacts with water to form hydrofluoric acid (HF\text{HF}HF) and carbon dioxide. Write a chemical equation for this reaction.
