Which effect occurs when pressure reduces reaction turnover rate in a catalytic converter?

A)Increased reactant surface residence time
B)Decreased adsorption equilibrium constants
C)Reduced active site blocking probability
D)Enhanced gaseous product conversion rate

💡 Explanation

Decreasing pressure shifts adsorption-desorption equilibria altering the catalytic converter dynamics. Equilibrium constants decrease because gas molecules desorb more easily from the catalyst surface, therefore reducing reaction rates, rather than increasing residence time or conversion.
