Which of the following is the balanced reaction, given the rate relationships below. a. rate = − 13   Δ[CH4] Δt = − 12   Δ[H2O] Δt = − Δ[CO2] Δt = 14   Δ[CH3OH] Δt
b. rate = − 12   Δ[N2O5] Δt = 12   Δ[N2] Δt = 15   Δ[O2] Δt
c. rate = − 12   Δ[H2] Δt = − 12   Δ[CO2] Δt = − Δ[O2] Δt = 12   Δ[H2CO3] Δt

a.

b.

c.

Explanation:

Hello,

In this case, since those rate relationships have the stoichiometric coefficient at the denominators of the fractions preceding each ratio and the negative terms account for reactants and positive for products, we have:

a.

b.

c.
