Interpretation Introduction

Interpretation:

The average reaction rate in moles of I2 consumed per liter per minute needs to be determined for the reaction,

I2+Cl22ICl2

Concept introduction:

In a chemical reaction, the reactants are written on the left side of the equation and the product is written on the right side.

The average rate of a reaction can be given by the formula,

Average reaction rate =Δ[reactant]Δt

Here, Δ[reactant] = change in the concentration of the reactant

Answer to Problem 47A

The average reaction rate for the moles of I2 consumed per liter per minute is 0.250minLmin

Explanation of Solution

Given in the reaction,

I2+Cl22ICl2, [I2] changes from 0.400 M at 0.00 min to 0.300 M at 4.00 min.

For this reaction,

Average reaction rate =Δ[reactant]Δt

Where, the change in the concentration of the reactant is given by Δ[reactant] and Δt is the change in time.

So, as [I2] changes from 0.400 M at 0.00 min to 0.300 M at 4.00 min in the reaction,

Therefore,

Δ[reactant][I2]=0.300M0.44M=0.100M

The change in time is Δt=4.00min0.00min=4.00min.

So, now we can use these values to calculate the average reaction rate.

Average reaction rate =Δ[reactant]Δt

=Δ[I2]Δt=0.100M4.00min=0.1004.00molLmin=0.0250minLmin

Therefore, the average reaction rate is 0.250minLmin

Conclusion

The average rate of the reaction is 0.250minLmin
