3 The study of which one of the followings guides to the mechanism of the reaction Order of reaction Rate of reaction Half-life period of reaction Rate determining step
4 For a chemical reaction in which one of the reactant also act as solvent, the order will be First order Third order Second order pseudo-first order
5 A reaction A- B is independent of concentration of reactant A. The order of reaction will be First order Second order Third order Zero order
6 When does average rate become equal to instantaneous rate of reaction At the start of reaction time interval is zero at the end of reactior time interval approaches zero
7 The slope of the graph is steepest at the beginning of reaction showing Rapid decrease in concentration of reactants Rapid increase in concentration of reactants Fast rate of reaction All of the above
8 Which property of liquid is measured by polarimeter Conductance Optical activity Refractiye Indéx Change in volume
9 Unit of the rate constant depends upon the Molecularity of reaction Order of reaction Concentration terms Number of reactants
10 The number of atoms or molecules whose concentrations determines the rate of a chemical reaction is called the Molecularity of the reaction specific activity of the reaction Order of the reaction rate constant of the reaction
11 In the reaction A+B→ Products, if B is taken in excess, then it is an example of Second order reaction zero order reaction Pseudo first order reaction first order reaction
