Which outcome occurs when a catalytic substrate experiences steric hindrance?

A)Reduced molecular reaction efficiency
B)Increased catalyst surface area
C)Enhanced product selectivity
D)Accelerated decomposition of catalyst

💡 Explanation

Reduced reaction efficiency occurs with steric hindrance, because it inhibits substrate-catalyst complex formation. The VdW repulsion forces destabilize the transition state, rather than accelerating decomposition; therefore, efficiency drops due to spatial constraints, not ideal mechanistic pathways.
