Dear student,

Ane 8 A + 2B C+D Torial [A] (M) [B] (m) Rate (m/s) 8.390 0.290 0.0208 0.390 6.580 0.0208 3 01780 0.290 0.0832 from nalo law hate = R [A] [B] Now, From taial & 0.0208 = K [0.390]{ [0.290]' 0.0208 - K [0.390]{ [0.58038 Dividing in by i), we get 0.0208 - 10. 880 14 0.290 0.0208 20 - 24

From laiad 6 and ③ we get 0.0208 = K [0:340] [0.2403 0.0832= K [0.780] K [0:240] 4. Dividing till by is, we get 0.0832 - 0.0208 0780 10.390 4 = (2) * So, the sale low is Rate = k [AJ? Order of aan wist A= 2. Ondea of aim wart B=0 Overall onder of reaction = 2+0=2. Subslicketing the value in larial 1. 0.0208 = K [0:390]? k= 0.0208 (0.390)2. -0.0208 0.1521 1 k = 0.136 M-13-1)

Please give a thumbs up to this answer.

With regards..
