Substitute natural gas can be synthesized by passing carbon monoxide and hydrogen over Ni or Co at 400°C. This process is an example of homogeneous catalysis.

Question

Substitute natural gas can be synthesized by passing carbon monoxide and hydrogen over Ni or Co at 400°C.  This process is an example of homogeneous catalysis.

Quizplus · Accepted Answer

The process mentioned is an example of heterogeneous catalysis as a solid catalyst (Ni or Co) is used to catalyze the reaction between gaseous reactants (CO and H2). Homogeneous catalysis involves a catalyst and reactants in the same phase (typically a liquid phase reaction with a soluble catalyst).
