Which outcome occurs when a platinum catalyst's surface area greatly reduces during a Fischer-Tropsch slurry reaction operating at 523K?

💡 Explanation

Greater mass transport limits occur because reduced surface area lowers availability of catalytic sites. Therefore the diffusion rate decreases, rather than equilibrium shifts because the equilibrium constant’s value remains unchanged without composition change within, assuming constant temperature.
