Chapter 13, Question 69 X Your answer is incorrect. Try again. Phosphine (PH3) decomposes into phosphorus and molecular hydrogen: 4PH3(g) → P4(9) + 6H2(9) Experiments show that this is a first-order reaction, with a rate constant of 1.73 x 102 s1 at 650°C. Which of the following statements are true? Select all that apply. V The overall reaction is elementary. O The data allow E, to be evaluated. The rate constant will be smaller than 1.73 x 102 s1 at 500°C. V The reaction PH3 - PH, + H might be the first, rate-determining step in the mechanism of this reaction.
