Question

Name Date 21. Rate data were collected for the following reaction at a temperature 2NO(g) + O3(g) → 2 NO: (g) Rate data have been determined at a particular temperature for the reaction in which all reactants and products are gases. Experiment # Initial [NO] 0.0125 M 0.0250M 0.0125M Initial [0] 0.0253 M 0.0253 M 0.0506M Initial Rate (M/s) 2.81 x 102 1.12 x 10- 5.62 x 102 Caleulate the order of the reaction with respect to each reactant. (5 points) b) Calculate the rate constant. (2 points) c) What is the rate law for the reaction.? (3 points)
please help and answer all 3 parts

Answer 1

Let the rate lave is given by & r = k C No2* [0] 4 - 0 - r' Is rate & 'K' is rate constant Using trial data 0 2.81410-2 - K [0.0125] [0.025399 Trial deta a 1:12X101 K Coroaso] * [o08535d Trial data ② 5.62 x 10-2 - K [0.0125[oosoogd - Dividing quietion 2 by ② g - Lootas Dividing equietion ② by 2 & 8.91 x 10-2 (2) (24 [y = 1 Putting at y value in equation ③ 1412X104. K [0.025.)? Co. 0253]' SK= 7083 or 7.1 x 100 M² s1 A

rate laul & Y= 7083 [NO]*[03] Order of reaction ith respect to [no] = x=27 Order of reaction with respect to [og] =y=+ Overall order = x+y=2+1=3
