Methane-and chlorine react to form chloroform and hydrogen chloride, like this: CetCl (g)+3HCI(g) CH (g)+3Cl,(@) The reaction is exothermic. Suppose a mixture of CH, CI, CHCI, and HCI has come to equilibrium in a closed reaction vess the perturbations in the table below will cause in the composition of the mixture in the vessel. Also decide whether the equilibr change in composition perturbation shift in equilibrium to the right to the left The temperature is raised. The pressure of CH4...
