Part A Review ConstantsI Periodic Table How many moles of N2O, will remain after 7.0 min? The first-order rate constant for the decomposition of N2 O Express the amount in moles to two significant digits. 2N2Os (g)+4NO2(g) +02(g) n1.6x10-3 mol at 70° C is 6.82 x 103 s-, Suppose we start with 2.80x102 mol of N2O5 (g) in a volume of 2.0 L You may want to reference (Page) Section 14.4 while completing this problem. Correct The rate of reaction depends on the current concentration of the reactant(s). At a constant volume, the number of moles can be equated to the concentration, and the relationship among the initial number of moles (n), tme(), the number of moles at time t (nt), and the rate constant (k) for a first-order reaction is as follows: ln(m) ln(no) -kt + = To solve for the number of moles at time t, we apply the relationship between the natural log and e to derive the following equation: kt Part B How many minutes will it take for the quantity of N205 to drop to 1.8×10-2 mol ?
