Question

For a reaction :2 NH subscript 3 left parenthesis straight g right parenthesis space rightwards arrow with Pt on top space straight N subscript 2 space left parenthesis straight g right parenthesis space plus 3 straight H subscript 2 left parenthesis straight g right parenthesis
Rate space equals space straight k

(i)Write the order and molecularity of this reaction.
(ii)Write the unit of k.

Answer

(i) This reaction is catalysed by Pt at high pressure. So, it is a zero-order reaction with molecularity 2.
(ii) The rate law expression for this reaction is Rate = k
Hence, the unit of k is mol L−1 s−1.
