Consider the reaction: cl2(g)+3f2(g)→2clf3(g) δ[cl2]/δt = -0.099 m/s .find δ[f2]/δt express your answer to two significant figures and include the appropriate units.

Hey there!

Given the reaction is :

Cl2(g) +  3 F2(g) = 2 ClF3(g)

The rate of a reaction is given by:

Rate = - Δ[Cl2] / Δt

=  (-1/3  Δ[F2] / Δt )   + ( 1/2  Δ[ClF3] / Δt )

Given that :  Δ[Cl2] / Δt  = - 0.099 M/s

From above rate law:

(- Δ[Cl2] / Δt ) =  ( -1/3  Δ[F2] / Δt )

( Δ[F2] / Δt )  = 3 *  ( Δ[Cl2] / Δt )

= 3 * ( - 0.099 ) =   - 0.297  M/s

Therefore:

Δ[F2]/Δt  = -0.297 M/s

Hope That helps!
