The rate Constant of reaction A B is 0.6 × 10–3 mole per second. If the Concentration of A is 5, then the concentration of B after 20 min is:
1. 1.08M
2. 3.60M
3. 0.36M
4. 0.72M
When the initial concentration of a reactant is doubled in a reaction, its half-life period is not affected. The order of the reaction will be:
1. 0
2. 1
3. 1.5
4. 2
1. | 12 | 2. | 16 |
3. | 32 | 4. | 10 |
1. | 1 | 2. | 2 |
3. | 3 | 4. | 0 |
