Question

Consider the following data to answer the next 4 questions.

[A] initial (M) [B] initial (M) Initial speed of the reaction (M / s)

0.2 0.1 5

0.2 0.2 10

0.6 0.2 30

3a. The order of the reaction with respect to [A] is__________.

3b. The order of the reaction with respect to [B] is__________.

3c. The net order of the reaction is__________.

3d. The value of k is (include units) is__________.

Answer 1

Rake law :- nate of reaction = K [A]^ [B]Y biven- S.NO [A] [B] speed (role) of reaction - Trail 1 0.2 ol 5 Trail 2 0.2 0.2 10 Trail 3 0.6 0.2 70 Putting these values in rate law expression - for Trail 1 - rate of reaction = K [AJ" [B]Y 5) 5EK (0.2)2(0.117 - 0

similarly for trail de 10 = K (0.23210.298 – for trail 3 - 30 = K (0.6)? (0.2) 9 - ③ diwidling eq@by eq0 - eq@ = 10K Corofa (0-234 Klosta (0.1) 9 9 do ga': (013 Ty=1

dividing eq 0 by eq@ ie - 5 sq - 30 = 106)* congly 10 *10.2) * (oxyg 33con le sue 7 (3)' = (3)* o (=) So, take low - I save of reaction= K [A]'[ø]' I) K (rate constant) = rate of reaction [A] [B' for trail 1, [AJ=0.2M, IBJ=0.im, rate - 5 mst. Soi k = 5 mst (0.8m)'(oim K = 250 Mist or eso morilst [ SI unit of M: moll'] Алла — (a) Order of reaction with respect to A=1 (6) order of the reaction with respect B=1 (C) Net Doder of the reaction = (1+1) = 8 (d) value of k = 250 mallst 1 or 250mist
