Shown Is a Concentration Versus Time Plot for a Reaction

question 82

Multiple Choice

Shown is a concentration versus time plot for a reaction involving gases A,B,and C.
-Over the time interval 300 to 400 seconds,the rate of reaction with respect to A is Δ[A]/Δt = 3.7 × 10^-5 M/s.Over the same time interval what is the rate of reaction with respect to B,Δ[B]/Δt?

• A)Δ[B]/Δt = Δ[A]/Δt = 3.7 × 10^-5 M/s
• B)Δ[B]/Δt = (1/4)(Δ[A]/Δt)= (1/4)(3.7 × 10^-5 M/s)= 9.2 × 10^-6 M/s
• C)Δ[B]/Δt = (1/2)(Δ[A]/Δt)= (1/2)(3.7 × 10^-5 M/s)= 1.8 × 10^-5 M/s
• D)Δ[B]/Δt = -(1/2)(Δ[A]/Δt)= -(1/2)(3.7 × 10^-5 M/s)= -1.8 × 10^-5 M/s
