Which risk increases when an industrial reactor uses excessive Nickel during catalytic hydrogenation?

💡 Explanation

Excessive nickel increases surface area above optimal levels, increasing the overall reaction rate above system design causing possible thermal runway because heat generation overcomes inherent cooling ability; therefore a runaway thermal equilibrium loss increases, rather than normal catalyst function that maintains parameters.
