Step-by-Step Verified Solution

Let the rate equation is  Rate  = k [ A ] _ [ B ] y Therefore, we can write 2 _ 10 _ 3 = k [ 0.1 ] x [ 0.1 ] y ..... (i) 4 _ 10 _ 3 = k [ 0.2 ] x [ 0.1 ] y ..... (ii) 1.6 _ 10 _ 2 = k [ 0.2 ] x [ 0.2 ] y ..... (iii)  (ii)  �  (i);  4 _ 10 _ 3 2 _ 10 _ 3 = k [ 0.2 ] x [ 0.1 ] y k [ 0.1 ] x [ 0.1 ] y _ 2 1 = ( 0.2 ) x ( 0.1 ) x = ( 2 1 ) x _ x = 1  (ii)  �  (iii);  4 _ 10 _ 3 1.6 _ 10 _ 2 = k [ 0.2 ] x [ 0.1 ] y k [ 0.2 ] x [ 0.2 ] y _ 1 4 = ( 0.1 ) y ( 0.2 ) y = ( 1 2 ) y _ y = 2 _  Rate  = k [ A ] 1 [ B ] 2 First order with respect to A while second order with respect to B.
