a$)$ Neatly draw a potential energy diagram for the following reaction with correct axis labels.

BaO$($s$)+$ H$2$O$($l$)->$Ba$($OH$)2($aq$)$

Your diagram does not need to be to scale. Also include each of the following labels:

o $$H $=+250$ kJ

o EA $=300$ kJ

o Activated complex

b$)$ Determine EA$($rev$)$ for the reverse reaction. Add this value to your diagram.

c$)$ On the above diagram, sketch and label a curve to represent the effect of a catalyst on the

reaction.
