The rаte expressiоn fоr а chemicаl reactiоn is rate = k [N2O]2 and the rate constant is 0.244 M–1 s–1 at 750 °C. A sample of N2O of concentration 0.200 M is allowed to decompose. Calculate the rate when 10% of the N2O has reacted. a. 2.6 x 10–3 M/s b. 7.9 x 10–3 M/s c. 9.8 x 10–5 M/s d. 4.9 x 10–3 M/s e. 4.4 x 10-2 M/s
