CHEMISTRY DECOMPOSITION

Question

For the decomposition of nitramide in aqueous solution at 25°C, the rate of the reaction is determined by measuring the appearance of N2O.

NH2NO2(aq)=N2O(g) + H2O(l)

At the beginning of the reaction the concentration of N2O is 0 M. After 187 min the concentration has increased to .183 M.

What is the rate of the reaction in Mol N2O/Min

Answer 1

0.183 mol N₂O was produced in 187 minutes. To find the reaction rate in mol N₂O/min, divide the amount of N2O produced by the time the reaction ran.

0.183 mol N₂O / 187 min. = 9,7861 x 10^-4 mol N₂O/min

But 0.183 mol N₂O has three significant figures, so the answer should also have three significant figures

9.79 mol N₂O/min is the correct way to report the answer.

Hope this helps
