Problem: The oxidation of SO2 to SO3 is accelerated by NO2. The reaction proceeds according to:NO2(g) + SO2(g) → NO( g ) + SO3 ( g )2NO(g) + O2(g) → 2NO2(g)Is this an example of homogeneous catalysis or heterogeneous catalysis?

FREE Expert Solution

We have to determine if the given example of a catalyst is homogenous catalysis of heterogenous catalysis.


A catalyst is a substance that speeds up chemical reaction without itself being consumed.

Based on the state of a catalyst in a chemical reaction, it can be classified as:

Homogenous catalyst: A catalyst that has the same state as the rest of the reactants and products.

Homogenous catalyst: A catalyst that has a different state as the rest of the reactants and products.

Problem Details
The oxidation of SO2 to SO3 is accelerated by NO2. The reaction proceeds according to:

NO2(g) + SO2(g) → NO( g ) + SO3 ( g )
2NO(g) + O2(g) → 2NO2(g)

Is this an example of homogeneous catalysis or heterogeneous catalysis?
