Answer to Question #184190 in General Chemistry for Natalia Pocica

Question

Decomposition of a N₂O₅ solution in water takes place via the following reaction:

2 N₂O₅ → 4 NO₂ + O₂

A scientist obtained some experimental data comparing the rate of decomposition and [N₂O₅]:

[N₂O₅]0.45 M, 0.90 M

Rate2.7 x 10^-4 M/s , 5.4 x 10^-4 M/s

Assuming that the rate law is in the following form:

Rate = k[N₂O₅]^a

Part A -

Determine the value of “a”.

Part B

Calculate “k”.

Part C

Calculate the rate of reaction when the concentration of N₂O₅ is 0.014 M.

Answer 1

Part A: 4

Part B: 2

$Part C: 8.4×10^-6$
