Given the following graph.
(a) Calculate `Delta H` for the reaction and energy of activation for the forward and backward reaction.

(b) Curve (2) is the energy profile in the presence of a catalyst. What is the energy of activation for the two reaction in the presence of a catalyst?
( c) Will the catalyst change the extent of the reaction?

Answer

`DeltaH=-10kJ//"mol";`
(b) `E_(f)=30 kJ //"mol"; E_(b)=40kJ//"mol";`
(c) `E_(f)=10kJ//"mol";E_(b)=20kJ//"mol"`
(d) no
