16.18 For the gas-phase reaction 2NO₂ + F₂ → 2NO₂F, the rate constant k is 38 dm³ mol-¹ s¹ at 27°C. The reaction is first- order in NO₂ and first-order in F₂. (a) Calculate the number of moles of NO₂, F2, and NO₂F present after 10.0 s if 2.00 mol of NO₂ is mixed with 3.00 mol of F₂ in a 400-dm³ vessel at 27°C. (b) For the system of (a), calculate the initial reaction rate and the rate after 10.0 s.

Question
16.18 For the gas-phase reaction 2NO₂ + F₂ → 2NO₂F, the
rate constant k is 38 dm³ mol-¹ s¹ at 27°C. The reaction is first-
order in NO₂ and first-order in F₂. (a) Calculate the number of
moles of NO₂, F2, and NO₂F present after 10.0 s if 2.00 mol of
NO₂ is mixed with 3.00 mol of F₂ in a 400-dm³ vessel at 27°C.
(b) For the system of (a), calculate the initial reaction rate and
the rate after 10.0 s.
