4. Reversible reactions. The forward and reverse rate constants (in appropriate units of moles, Liters, and min) for the reaction A+B=C + D have been measured at three different temperatures (see table). k (forward)k (reverse) 473 1.3E+00 1.2E-11 T(K) 673 873 1.9E+03 9.6E+04 9.4E-06 1.5E-02 (a) From these results, determine the activation energy of the two constants and the overall heat of reaction. (b) Draw a potential energy Vs reaction coordinate diagram. (c) The A+B=C + D reaction is carried out at 473 K in a 1L batch reactor, which initially is loaded with a gaseous mixture of 1 mole A and 1 mole B. Calculate and plot the evolution of concentrations of A, B, C, and Das a function of time and determine the composition of the system as it approaches equilibrium
