AP Chemistry
5.1 Reaction Rates
A student investigates the gas-phase decomposition of dinitrogen pentoxide at a constant temperature in a rigid container, as represented by the balanced equation below:
\(2\text{N}_2\text{O}_5\text{(g)} \rightarrow 4\text{NO}_2\text{(g)} + \text{O}_2\text{(g)}\)
At a particular instant during the reaction, the student measures the rate of concentration change for each species. Which of the following correctly ranks the absolute rates of concentration change, \(\left|\dfrac{\Delta[\text{X}]}{\Delta t}\right|\), for the three gases at this instant, from greatest to least?
\(2\text{N}_2\text{O}_5\text{(g)} \rightarrow 4\text{NO}_2\text{(g)} + \text{O}_2\text{(g)}\)
