WebThe net rate of formation of any species is equal to its rate of formation in the forward reaction plus its rate of formation in the reverse reaction: rate net = rate forward + rate reverse. At equilibrium, rate net 0 and the rate law must reduce to an equation that is thermodynamically consistent with the equilibrium constant for the reaction. WebNext we can write the rate law for the reverse reaction. So the rate of the reverse reaction is equal to the rate constant, and we'll put in a subscript R here. So that's the rate constant for the reverse reaction. And in the reverse reaction, 2X combines to form X2. So this would be times the concentration of X.
