Question

Find the rate law of `2NO+2H_2\rarrN_2+2H_2O` for the following table below?

Answer 1

`R=k[NO]^2[H_2]^1`

`\color(indianred)(\text(By the way -- the equation has a typo, it should be))`
`\color(lightcoral)(2NO+2H_2\rarrN_2+2H_2O)`

Explanation:

Given `[NO]^m[H_2]^n`, I found `m=2` (Khan Academy method)
and `n=1`. Therefore the rate law is

`R=k[NO]^2[H_2]^1`
