Acetylene and oxygen react to form carbon dioxide and water, like this: 2C,H,($)+50,($) 400,(9)+2H,0() Suppose a mixture of C2H2, 02, CO2 and H2O has come to equilibrium in a closed reaction vessel. Predict what change, if any, the perturbations in the table below will cause in the composition of the mixture in the vessel. Also decide whether the equilibrium shifts to the right or left. perturbation change in composition shift in equilibrium O to the right The pressure of O2 will ? to the left Some C2H2 is added. The pressure of CO2 will ? O (none) to the right The pressure of CH will ? Some CO2 is removed. O to the left The pressure of O2 will ? O (none)
