Question

Write the expression for the rate of formation of the products and the rate of consumption of the reactants for the reaction HO(g) -> H2(g) + O2(g) How would you write this?

My high school teacher gave us this question and I don't recall going over this in class...

Answer 1

I think your teacher means this …

Explanation:

For the reaction

`"2H"_2"O" → "2H"_2 + "O"_2`

the rate of reaction is

`"Rate of reaction" = "-"1/2(Δ["H"_2"O"])/(Δt) = "+"1/2(Δ["H"_2])/(Δt) = "+"1/1(Δ["O"_2"])/(Δt)`

In other words, you divide the rates of appearance or disappearance of each species by their coefficients in the balanced equation.
