Calculate the standard enthalpy change for the following reaction.

Question

CO(g) + Cl₂(g)COCl₂(g)

Answer 1

∆H_fº = standard enthalpy of formation. These values can be looked up on the internet or in a book.

∆H_fº COCl₂(g) - ([∆H_fº CO(g) + ∆H_fº Cl₂(g)]) = ∆Hº_reaction

Look up the necessary values and plug them in to solve the problem.
