WebAt room temperature, the rate of reaction is slower in the absence of a catalyst with its activation energy being 76 kJ mol-1. In the presence of catalyst, iodide ion (I - ), the reaction is faster since the activation energy decreases to 57 kJ mol -1 . WebThe rate of a surface-catalyzed reaction increases with the surface area of catalyst in contact with the reactants. Therefore, the solid support inside of a catalytic converter is designed to have a very high surface area, hence the porous, honeycomb-like appearance.

How does a catalyst increase the rate of reaction?

In the presence of catalyst, iodide ion (I - ), the … WebAnd we would see a huge plume of gas come out of the reaction flask. So the addition of a catalyst, in this case it was the iodide, an ion, increased the rate of the reaction. A catalyst increases the rate of reaction by effecting the kinds of collisions that occur between particles. And a catalyst increases the rate of reaction without being ... how many social classes did babylonia have
