Question
P17B.8 The following data have been obtained for the decomposition of
N,O,(g) at 67°C according to the reaction 2 N,O,(g) → 4NO,(g) + O,(g).
Identify the order of the reaction with respect to N,O, and calculate the rate
constant and the half-life of N,O,. Hint: It is not necessary to obtain the result
graphically; you may do a calculation by making estimates of the rates of
change of concentration.
