Which risk increases when chemical equilibrium shifts in exothermic catalytic converter reaction?

💡 Explanation

When temperature rises excessively due to an equilibrium shift favoring exothermic reactions, enhanced surface diffusion causes catalyst sintering because increased atomic mobility reduces the surface area over time, diminishing activity. Therefore, sintering risk increases, rather than reduced conversion or pressure, which result from different mechanical malfunctions or non-optimal parameter states.
