Question

What is the order of the following reaction ? 2 H 2 ​ O 2 ​ ( l ) → 2 H 2 ​ O ( l ) + O 2 ​ ( g ) , if rate = k [ H 2 ​ O 2 ​ ]

TestHub · Accepted Answer

The rate law for the given reaction is provided as rate = $k [H_{2} O_{2}]$ .

The order of a reaction is defined as the sum of the exponents of the concentration terms in the rate law expression.

In this rate law, the exponent of the concentration of $H_{2} O_{2}$ is $1$ .

Therefore, the order of the reaction is $1$ .

Answer: $1$
