WebConsider now a reaction in which the coefficients are different: A+3B→2D It is clear that [B] decreases three times as rapidly as [A], so in order to avoid ambiguity when expressing the rate in terms of different components, it is customary to divide each change in concentration by the appropriate coefficient: rate=−Δ [A]/Δt=−Δ [B]/3Δt=Δ [D]/2Δt Webreaction rate. is the concentration of the . reactants. An increase in concentration means an increase in the number of particles in the reaction. This results in an increase in the collision frequency.
