The reaction must shift towards the products to reach equilibrium. The reaction must shift towards the reactants to reach equilibrium .
Carbon monoxide reacts with chlorine to from phosgene.
Explain why the change in the N2 concentration that occurs when the following reaction comes to equilibrium is related to the change in the H2 concentration. Derive an equation that describes the relationship between the changes in the concentrations of the two reagents. Calculate the concentrations of PCl5, PCl3 and Cl2 that are present when the following gas phase reaction comes to equilibrium. Calculate the percent of the PCl5 that decomposes when the reaction comes to equilibrium. Explain the difference between the results of this calculation and that obtained in Section 10.7.
