The decomposition of `NH_3`on the surface of metal like platinum is a zero order reaction. What is the unit of the rate constant k for this reaction?

Explanation

`2 (NH)_(3)harr(N)_(2(g)+3 (H)_(2(g)`
`rate =-(1)(2) (d)(N) (H)_(3)(dt)=(d)[(N)_(2(dt)=(1)(3) (d)[(H)_(2)(dt)`
`rate =(k) as it is a zero order reaction`
`(d)[(N)_(2)(dt)=2.5 * 10^(-2)` `(mol)^(-(1) (L)(s)^(-1)`
&`(d)[(H)_(2)(dt)=3 * 2.5 * 10^(-4)=7.5 * 10^(-4) (mol)^(-1) (L)(s)^(-1)`
