Catalyst Effect on Reaction Energy Profile
The decomposition of N2O5 has an activation energy of 103 kJ/mol and a ΔH of -57 kJ/mol. After a catalyst is added, the activation energy is reduced to 62 kJ/mol. Which statement describes the resulting reaction energy profile?
A
Higher reactant energy; ΔH unchanged at -57 kJ/mol
B
Lower transition state energy; ΔH unchanged at -57 kJ/mol
C
Lower transition state energy; ΔH = -98 kJ/mol
D
Same transition state energy; lower product energy
