Potential energy profile for the decomposition of \(\text{H}_2\text{O}_2\text{(aq)}\) with and without a catalyst.
Potential energy profile for the decomposition of \(\text{H}_2\text{O}_2\text{(aq)}\) with and without a catalyst.
The potential energy profile for the reaction represented below is shown in the diagram. The reaction was conducted under two different conditions: uncatalyzed (solid curve) and catalyzed (dashed curve).

\[ 2\text{H}_2\text{O}_2\text{(aq)} \rightarrow 2\text{H}_2\text{O(l)} + \text{O}_2\text{(g)} \]

Based on the diagram, which of the following correctly compares the activation energy, \(E_a\), and the enthalpy change, \(\Delta H\), of the catalyzed pathway to those of the uncatalyzed pathway?
