Question

Nitric oxide reacts rapidly with unstable nitrogen trioxide (NO3) to form NO2: $$ Calculate the numeric value of the rate constant for the above reaction from the data in the table below. Initial Reaction Rates for the Formation of NO2 by the Reaction of NO with NO3 at 298 K.

Experiment [NO]0 (M) [NO3]0 (M) Initial Reaction Rate (M/s)

1 1.40×10-3 1.40×10-3 2.80×104

2 2.80×10-3 1.40×10-3 5.60×104

3 2.80×10-3 2.80×10-3 112000

Answer 1
