The reaction between A and B is first order with respect to A and zero order with respect to B.Phil. in the blanks in the following table:

Experiment	[A]/mol L-1	[B]/mol L-1	Initial rate/mol L-1 min-1
I	0.1	0.1	2.0 × 10-2
II	-	0.2	4.0 × 10-2
III	0.4	0.4	-
IV	-	0.2	2.0 × 10-2

As reaction is first order with respect to A and zero Order with respect to B. Then changing the concentration of B won’t affect the rate of reaction and increasing concentration of A ‘n’ times will increase the rate by ‘n’ times. By this logic lets fill the table- In first blank space concentration of A will be 0.2 mol L^-1 because the rate is doubled. In second blank space, Rate will be 8 × 10^-2mol L^-1min^-1 because the concentration of A is increased 4 Times. In third blank space concentration of A will be 0.1 mol L^-1 because the rate is same as in experiment I.
