Question

The first-order rate constant for the decomposition of N2O5,

2N2O5(g) yields 4NO2(g)

at 70∘C is 6.82 x 10-3 s-1 . Suppose we start with 2.30×10−2 mol of N2O5(g) in a volume of 1.8 L . 

How many moles of N2O5 will remain after 7.0 minutes?

Expert Solution
Step 1

Given that :

Rate constant = 6.82 x 10-3 s-1

Initial concentration = 2.30×10−2 

Volume = 1.8 L

We have to calculate the moles of N2O5 will remain after 7.0 minutes.
