a) Which of the following is NOT a rate?

kg/hour
mol/g
mol/second

g/minute

b) Which is a valid way to express reaction rate for N2(g) + 3 H2(g) → 2 NH3(g)?

rate = - Δ[N2]/Δt, rate = -1/3 Δ[H2]/Δt, rate = 1/2 Δ [NH3]/Δt
rate = Δ[N2]/Δt, rate = 1/3 Δ[H2]/Δt, rate = -1/2 Δ [NH3]/Δt
rate = - Δ[N2]/Δt, rate = -3 Δ[H2]/Δt, rate = 2 Δ [NH3]/Δt
rate = Δ[N2]/Δt, rate = 3 Δ[H2]/Δt, rate = -2 Δ [NH3]/Δt
