| 2 | Which technique is used ot determine the absorption of radiations. | Spectrometry dilatometer method Refractometric method Optical rotation method |
| 3 | Which properties of liquid is measured by polarimeter | Conductance Refractive index Optical activity Change in volume |
| 4 | Dilatometer method is useful for the reactions that involve. | Ionic species Where reactant absorb U.V. visible or infrared radiations Small volume changes in solutions Change in refractive indices |
| 5 | the rate of reaction when concentration of reactants are taken unity is called. | Average rate Instantaneous rate Specific rate Rate equation |
| 6 | The unit of the rate constant is the same as that of the rate of reaction in | First order reaction Second order reaction Zero order reaction Third order reaction |
| 7 | With increases of 10 oC temperature the rate of reaction doubles. This increase in rate of reactions is due to. | Decrease in activation energy of reaction Decrease in the number of collisions between reactant molecules Increase in activation energy of reactants Increase in number of effective collisions |
| 8 | The rate of reaction | Increase as the reaction proceeds Decreases as the reaction proceeds Remains the same as the reactions proceeds May decrease or increase as the reaction proceeds |
| 9 | In zero order reaction, the rate is independent of. | Temperature of reaction Concentration of reactants concentration of products None of these |
