Answer:

Rate : [tex] k [H_2]^2 [O_2][/tex]

Explanation:

What is rate law expression?

  • It may be defined as the rate of reaction in the terms of molal concentration of reactant with each term raised to some power.

For example consider a chemical reaction,

  • aA + bB → cC + dD

Rate of reaction= [tex]k[A]^a[B]^b[/tex]

Where:

  • k is rate constant
  • [A] and [B] are the concentrations of the reactants.
  • a and b are the reaction orders.

Also, the reaction orders may or may not be equal to the stoichiometric coefficient.
