MISSED THIS? Read Section 15.4 (Pages 642 - 650); Watch KCV 15.4 The data below show the concentration of N₂O5 versus time for the following reaction: N₂O5 (g) → NO3(g) + NO₂(g) Time (s) [N₂O5] (M) 0 1.000 25 0.822 50 75 100 125 150 175 200 0.677 0.557 0.458 0.377 0.310 0.255 0.210 ✓ Correct The rate law for this decomposition reaction is rate = k[N₂O5]" where k is the rate constant and n is the reaction order. Looking at the concentration change over time, you can see that the half-life of this reaction is constant, which indicates that it might be first order. To confirm this hypothesis, plot In [N₂05] vs. time. This plot generates a straight line, so the reaction must be first order in N₂O5. Part B k= Determine the value of the rate constant. Express the rate constant to three significant figures Part C IVE ΑΣΦ Submit Predict the concentration of N₂O5 at 270 s.
