Problem: Given the following balanced chemical equation 3 O2 + 2 CH3OH → 2 CO2 + 4 H2OHow is the rate of appearance of H2O related to the rate of disappearance of O2? 

FREE Expert Solution

Recall that for a reaction aA  bB, the rate of a reaction is given by:


Rate=-1aΔ[A]Δt=1bΔ[B]Δt


where:

Δ[A] = change in concentration of reactants or products (in mol/L or M), [A]final – [A]initial

Δt = change in time, tfinal – tinitial




Reaction: 3 O2 + 2 CH3OH → 2 CO2 + 4 H2O


H2O is a product, the rate with respect to H2O is positive (+) since we’re gaining products.

O2 is a reactant, the rate with respect to O2 is negative (–) since we’re losing reactants.
