← ScienceWhich outcome results when positive catalyst is added?
A)Reaction activation energy decreases directly✓
B)Reactant concentration reaches equilibrium slower
C)Product energy increases overall process
D)The reaction enthalpy changes significantly
💡 Explanation
The reaction's activation energy decreases because a catalyst provides an alternative reaction pathway utilizing a transition state that requires less energy; therefore, activation energy drops; rather than an enthalpy differences at constant temperature.
