How is Surface catalyst(heterogeneous) and homogeneous catalyst different? I'm in 10th grade chemistry and I don't understand it.

    Ok, you obviously have a misunderstanding.

    Heterogeneous catalysts: this is when the catalyst and the reactants are NOT in the same phase, an example being a solid catalyst(even finely divided particles) acting on a gaseous reacation.

    Homogenous catalysts: The catalyst is in the same phase as the reactants. example: Sulfuric acid as as catalyst mixed with a liquid reactant to make a chemical ester.

    Thank you!
