What advantage does a heterogeneous catalyst provide over a homogeneous catalyst in industrial processes? a heterogeneous catalyst provides a higher reaction rate. a heterogeneous catalyst can be easily separated from reactants. a heterogeneous catalyst raises the activation energy higher. a heterogeneous catalyst provides an alternate reaction pathway.

A heterogeneous catalyst can be easily separated from reactants.

Explanation:

In general catalysts as substances that lower the activation energy for a given reaction. Catalysts can be broadly classified into two categories:

Homogenous and Heterogenous catalyst

Homogeneous catalysts are those that occur in the same phase as the reaction mixture while heterogeneous catalyst occur in a phase which is different from the reactants typically as a solid added to a gas or a liquid reactant.

The advantage of heterogeneous catalyst is that they can be easily recovered   from the reaction mixture through a simple filtration process. This is particularly important in industries that employ expensive catalysts.

i'm assuming that the correct answer is indeed the first one/ "a"..

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
