← ScienceWhich outcome occurs when catalyst is absent from reactants?
A)Higher activation energy reaction proceeds✓
B)Lower activation energy becomes prevalent
C)Reaction rate is exponentially improved
D)Equilibrium concentrations shift dramatically
💡 Explanation
A higher activation energy is observed if catalyst is absent due to the chemical kinetics influencing the energy required for reactant reactants by the mechanism of altering the reaction pathway; therefore overall process will proceed slowly rather than with higher temperature affecting equilibrium significantly.
