Answer 1

and order wort [B] let the order wort [A] be 'a' be 'b', then sate law will be rate = K[A)" [BB] writing rate Law for each trial seperately as 1.48103 = k10.20)" (0.030) 2.9x103 = K (0.20) (0.060) 5.8 x 103 = k10.40) (0.030) 1 Di we Dividing the 0.030 1.4 x 103 2.9 x 103 0.20 lo, we get- (6030) = ( ) » (approax) 1.4x10 3 Dividing 0 1 0 , we get- Luxo? (2:20) = () (approas) 0.060 0.40 5.8 x 103 b = 1 a = 2 Thus, rate law will be- Rate = k [A] [B] Please Rate
