There are two reactions shown below. reaction 1: $ \text{N}_2(g) + 3\text{H}_2(g) \rightleftharpoons 2\text{NH}_3(g) $ reaction 2: $ 2\text{O}_3(g) \rightleftharpoons 3\text{O}_2(g) $ For reaction 1, a finely powdered iron catalyst is employed. For reaction 2, a vaporised tetrachloromethane catalyst in ultraviolet light is employed. Which statement about the catalysts used is correct?
- ABoth reaction 1 and reaction 2 use a heterogeneous catalyst.
- BBoth reaction 1 and reaction 2 use a homogeneous catalyst.
- CReaction 1 uses a heterogeneous catalyst and reaction 2 uses a homogeneous catalyst.
- DReaction 1 uses a homogeneous catalyst and reaction 2 uses a heterogeneous catalyst.
