For the single step reaction: A $+$ B $->2$C $+25$ kJ

If the activation energy for this reaction is $35\mathrm{.}8$ kJ$,$ sketch an energy vs$.$ reaction co$-$ordinate diagram for this reaction. Be sure to label the following on your diagram: each of the axes, reactant compounds and product compounds, enthalpy of reaction, activation energy of the forward reaction with the correct value, activation energy of the backwards reaction with the correct value and the transition state. $(8$ marks$)$

On the same sketch you drew, after the addition of a homogeneous catalyst, show how it would change the graph. Label any new line "catalyst" and label any new activation energy. $(2$ marks$)$ Please actually draw the diagram, don't just explain how to draw it$.$
