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.
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 | 0.2 | 4.0 × 10-2 |
III | 0.4 | 0.4 | 8.0 × 10-2 |
IV | 0.1 | 0.2 | 2.0 × 10-2 |
