For the progress of the following elementary reaction: NH_3(g) + Cl_2(g) - NH_2Cl(g) + HCl(g) Delta H_rxn = 4.0 kJ/mol E_a = 22.0 kJ/mol a. Create a potential energy profile. Be sure to label the reactants, the products, the transition state, the enthalpy reaction and the activation energy. b. Draw a possible structure of the transition state, using dotted line to show the forming/breaking bond(s). For the following reaction 2A_2 + B_2 - 2C. The following mechanism has been proposed: step 1 (very slow) A_2 + B_2 rightarrow R + C step 2 (fast) A_2 + R rightarrow C Suggest the rate law for the overall reaction based on the mechanism.
