Hydrogen peroxide decomposes spontaneously to yield water and oxygen gas according to the reaction equation 2H2O2(aq)⟶2H2O(l)+O2(g)2H2O2(aq)⟶2H2O(l)+O2(g) The activation energy for this reaction is 75 kJ⋅mol−1.75 kJ⋅mol−1. In the presence of a metal catalyst, the activation energy is lowered to 49 kJ⋅mol−1.49 kJ⋅mol−1. At what temperature would the non‑catalyzed reaction need to be run to have a rate equal to that of the metal‑catalyzed reaction at 25 ∘C? T= K
