How many moles of N2O5 will remain after 4.0 min ?Express the amount in moles to two significant digits. The first-order rate constant for the decomposition of \( \text{N}_2\text{O}_5 \),\[ 2\text{N}_2\text{O}_5(g) \rightarrow 4\text{NO}_2(g) + \text{O}_2(g) \]at 70°C is \( 6.82 \times 10^{-3} \, \text{s}^{-1} \). Suppose we start with \( 2.60 \times 10^{-2} \, \text{mol} \) of \( \text{N}_2\text{O}_5(g) \) in a volume of 2.5 L.

Rate = 6.82 x 10-3 s-1 2.60 x 10-2 moles in 2.5L t = 4 min = 240s

Question

How many moles of N2O5 will remain after 4.0 min ?

Express the amount in moles to two significant digits.

The first-order rate constant for the decomposition of \( \text{N}_2\text{O}_5 \),

\[ 2\text{N}_2\text{O}_5(g) \rightarrow 4\text{NO}_2(g) + \text{O}_2(g) \]

at 70°C is \( 6.82 \times 10^{-3} \, \text{s}^{-1} \). Suppose we start with \( 2.60 \times 10^{-2} \, \text{mol} \) of \( \text{N}_2\text{O}_5(g) \) in a volume of 2.5 L.
