Are the concentrations of phosphorus pentachloride, PCl5,PCl5, and phosphosphorus trichloride, PCl3,PCl3, constant or changing at equilibrium?
The concentration of PCl5PCl5 is constant, and the concentration of PCl3PCl3 is changing at equilibrium.
The concentration of PCl5PCl5 is changing, and the concentration of PCl3PCl3 is constant at equilibrium.
The concentrations of both PCl5PCl5 and PCl3PCl3 are constant at equilibrium.
The concentrations of both PCl5PCl5 and PCl3PCl3 are changing at equilibrium.
which one is correct please explain
At equilibrium, the rate of forward reaction is equal to the rate of backward reaction. So, the rates of consumption of PCl5 and PCl3 respectively are equal to the rates of formation of these compounds. So, the concentration of both of these compounds remain constant.
So, the third statement is correct.
