Give the relative rates of disappearance of reactants and formation of products for each of the following reactions. (a) 2 O3(g) → 3 O2(g) (b) 2 HOF(g) → 2 HF(g) + O2(g)

(a)

Interpretation Introduction

Interpretation: The rate of disappearance of reactants and formation of products has to be given.

Concept introduction:

Relative rates and stoichiometry: During a chemical reaction, amounts of reactant decrease with time and amounts of products increases.

Reaction Rate = - 1coefficientΔ[reactants]Δt = +1coefficient Δ[products]Δt

Reaction Rate = - 12Δ[O3]Δt = +13 Δ[O2]Δt

Explanation

The relative rate of the chemical reaction is given as

Reaction Rate = - 1coefficientΔ[reactants]Δt = +1coefficient Δ[products]ΔtGivenreaction: 2O3(g)3O2(g)Reactant: 2O3(g)Product: 3O2(g) The red colored numbers represent the stoichiometry coefficients.Reaction Rate = - 12Δ[O3]Δt = +13 Δ[O2]Δt

The relative rate of the given chemical reaction is,

Reaction Rate = - 12Δ[O3]Δt = +13 Δ[O2]Δt

(b)

Interpretation Introduction

Interpretation: The rate of disappearance of reactants and formation of products has to be given.

Concept introduction:

Relative rates and stoichiometry: During a chemical reaction, amounts of reactant decrease with time and amounts of products increases.

Reaction Rate = - 1coefficientΔ[reactants]Δt = +1coefficient Δ[products]Δt

Reaction Rate = - 12Δ[HOF]Δt = +12 Δ[HF]Δt=+11 Δ[O2]Δt

Explanation

The relative rate of the chemical reaction is given as

Reaction Rate = - 1coefficientΔ[reactants]Δt = +1coefficient Δ[products]ΔtGivenreaction: 2 HOF(g)2HF(g) +1O2(g)Reactant: 2 HOF(g)Product: 2HF(g) +1O2(g)The red colored numbers represent the stoichiometry coefficients.Reaction Rate = - 12Δ[HOF]Δt = +12 Δ[HF]Δt=+11 Δ[O2]Δt

The relative rate of the given chemical reaction is,

Reaction Rate = - 12Δ[HOF]Δt = +12 Δ[HF]Δt=+11 Δ[O2]Δt
