Textbook Problem

# Give the relative rates of disappearance of reactants and formation of products for each of the following reactions. (a) 2 NO(g) + Br2(g) → 2NOBr(g) (b) N2(g) + 3H2(g) → 2NH3(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

Explanation

The relative rate of the chemical reaction is given as,

â€‚Â ReactionÂ Rateâ€‰Â =Â -Â 1coefficientÎ”[reactants]Î”tÂ =Â +1coefficientÂ Î”[products]Î”tGivenâ€‰reaction:Â 2NO(g)Â +Â 1Br2(g)â†’2NOBr(g)Reactant:Â 2NO(g)Â +Â Br2(g)Product:Â 2NOBr(g)Â TheÂ redÂ coloredÂ numbersÂ representÂ theÂ stoichiometryÂ coefficients
