  • Question 1
    4 / -1

    What will be the order of the reaction if doubling the concentration of a reactant increases the rate by a factor of 4 and trebling the concentration of the reactant by a factor of 9 ?

  • Question 2
    4 / -1

    If the half time for a particular reaction is found to be constant and independent of the initial concentration of the reactants then reaction is of ...

  • Question 3
    4 / -1

    The rate of reaction A + B + C → Products is given by r = K[A][B]o[C]. If A is taken in large excess, the order of the reaction would be

  • Question 4
    4 / -1

    For a reaction 2A + B → Products, the active mass of B is kept constant and that of A is doubled. The rate of reaction will then

  • Question 5
    4 / -1

    The conversion of A → B follows second order kinetics. Doubling the concentration of A will increase the rate of formation B by a factor of

  • Question 6
    4 / -1

    Ethyl acetate is hydrolysed in alkaline medium, its order of a reaction and molecularity are respectively

  • Question 7
    4 / -1

    The given reaction 2FeCl3 + SnCl2 → 2FeCl2 + SnCl4 is an example of ________ reaction

  • Question 8
    4 / -1

    If concentration of reactants is increased by ‘x’, then rate constant K becomes ..

  • Question 9
    4 / -1

    The rate constant is given by equation K = p.z.e-Ea/RT which factor should register a decrease for the reaction to proceed more rapidly ?

  • Question 10
    4 / -1

    The time for half life of a certain reaction A → Products, is one hour. When the initial concentration of the reactant A is 2 mol L-1 how much time does it take for its concentration to come from 0.50 to 0.25 mole L-1 if it is a zero order reaction ?
