hosphine (PH3) decomposes into phosphorus and molecular hydrogen: 4PH3(g) → P4(g) + 6H₂(g) xperiments show that this is a first-order reaction, with a rate constant of 1.73 x 10-2 s1 at 650°C. Which of the following statements are true? Select all that apply. The overall reaction is elementary. The data allow E₂ to be evaluated. The rate constant will be smaller than 1.73 x 10-² s¹ at 500°C. The reaction PH3 → PH2 + H might be the first, rate-determining step in the mechanism of this reaction.

Nitrosyl bromide decomposes by the reaction 2 NOBr(g) → 2 NO(g) + Br₂(g). Show that the following data are consistent with a second-order reaction and determine the second-order rate constant for the reaction. Students may do this by plotting the data three different ways. For each plot, time goes on the x-axis. A zero-order reaction is linear when [NOBr] on the y-axis. A first-order reaction is linear when In [NOBr] is on the y-axis.
