Answer to Question #47406 in Chemistry for Ethan Leib

Question

The first-order rate constant for the decomposition of N2O5{\rm N_2O_5},
2N2O5(g)→4NO2(g)+O2(g)2{\rm N_2O_5}(g) \rightarrow 4{\rm NO_2}(g) + {\rm O_2}(g),
at 70∘C^\circ {\rm C} is 6.82×10−3s−16.82 \times 10^{ - 3}\;{\rm{s}}^{ - 1}. Suppose we start with 2.80×10−2mol{\rm mol} of N2O5(g){\rm N_2O_5}(g) in a volume of 1.6L{\rm L} . How many moles of N2O5{\rm N_2O_5} will remain after 5.0min{\rm min} ?
