🤓 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:

$\overline{){\mathbf{Rate}}{\mathbf{=}}{\mathbf{-}}\frac{\mathbf{1}}{\mathbf{a}}\frac{\mathbf{\Delta }\mathbf{\left[}\mathbf{A}\mathbf{\right]}}{\mathbf{\Delta t}}{\mathbf{=}}\frac{\mathbf{1}}{\mathbf{b}}\frac{\mathbf{\Delta }\mathbf{\left[}\mathbf{B}\mathbf{\right]}}{\mathbf{\Delta t}}}$

where:

Δ[A] = change in concentration of reactants or products (in mol/L or M)

Δt = change in time
