The rate Constant of reaction A → B is 0.6 × 10–3 \(\mathrm{molL}^{-1} \mathrm{~S}^{-1}\). If the Concentration of A is 5M, 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. | 1 | 2. | 2 |
| 3. | 3 | 4. | 0 |
For the reaction,
the value of rate of disappearance of N2O5 is given as 6.25 x 10-3mol L-1s-1.The rate of formation of NO2 and O2 is given respectively as:
| 1. | 6.25 × 10-3 mol L-1s-1 and 6.25 × 10-3 mol L-1s-1. |
| 2. | 1.25 × 10-2 mol L-1s-1 and 3.125 × 10-3 mol L-1s-1. |
| 3. | 6.25 × 10-3 mol L-1s-1 and 3.125 × 10-3 mol L-1s-1. |
| 4. | 1.25 × 10-2 mol L-1s-1 and 6.25 × 10-3 mol L-1s-1. |
