Which mechanism hinders complete conversion in catalytic cracking?

💡 Explanation

Catalyst active site degradation hampers cracking when coke or contaminants block sites, because it reduces catalytic activity, therefore overall conversion declines rather than a shift in equilibrium which primarily affects reversible reactions.
