The equilibrium constant, Kc, for the following reaction is 55.6 at 698 K: H2(g) + I2(g) ---------->2HI(g) 1) Calculate the equilibrium concentrations of reactants and product when 0.309 moles of H2 and 0.309 moles of I2 are introduced into a 1.00 L vessel at 698 K. [H2] = M? [I2] = M? [HI] = M? 2.The equilibrium constant, K, for the following reaction is 1.20×10-2 at 500 K: PCl5(g)------->PCl3(g) + Cl2(g) An equilibrium mixture of the three gases in a...
21C.1(a) The reaction of propylxanthate ion in acetic acid buffer solutions has the mechanism A− +H+→P. Near 30 °C the rate constant is given by the empirical expression kr=(2.05×1013) e−(8681K)/T dm3mol−1 s−1. Evaluate the energy and entropy of activation at 30 °C. 21C.1(b) The reaction A− +H+→P has a rate constant given by the empirical expression kr=(6.92×1012)e−(5925K)/T dm3mol−1 s−1. Evaluate the energy and entropy of activation at 25 °C. Please explain why they calculated H=E-RT like that like why is...
