Chemistry Practice Problems Average Rate of Reaction Practice Problems Solution: Consider the reaction: Cl2(g) + 3F2(g) → 2ClF3(g)....

🤓 Based on our data, we think this question is relevant for Professor Du's class at UGA.

Solution: Consider the reaction: Cl2(g) + 3F2(g) → 2ClF3(g).Given that Δ[Cl2]/Δt = -0.054 M/s. Find the rate of the reaction.

Problem

Consider the reaction: Cl2(g) + 3F2(g) → 2ClF3(g).

Given that Δ[Cl2]/Δt = -0.054 M/s. Find the rate of the reaction.

Solution

We’re being asked to calculate the rate of the reaction for the following reaction:

Cl2(g) + 3 F2(g)  2 ClF3(g)


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)

Δt = change in time
