at equilibrium, concentration - ANSWER-stops changing The equilibrium constant, Kp, for the following reaction is 1.04×10-2 at 548 K. Calculate Kc for this reaction at this temperature. - ANSWER-Use the equation kp=Kc(RT)^(change in moles of gas) Or, use kc=Kp(RT)^(-change in moles of gas) *remember, r is 0.0821 L/m* if the change in moles is equal to 0, kp=kc if Kc is less than one, will it be product favored or reactant favored at equilibrium? - ANSWER-reactant favored if Kc is gre...
