C) A+BC --> AC + B is the rate determining step because it is the step that has the highest activation energy                                            (largest hill to overcome on the diagram). This step will be the slowest step.

D) rate = k [A][BC]  .....since the collision of A and BC is part of the rate-determining step, it determines the rate of                                        the rxn (the rxn can't go faster than the slowest step).

would the reaction be endo or exothermic?

The rxn would be endothermic.  We can tell that by looking at the energy level of the reactants (stage 1) versus the energy level of the final product (stage 5). Since the products are higher in energy we must put energy into (endo-) the reaction to make the product (CD).
