    The overall activation energy Ea in terms of rate law is: 

    Solutions

    From Arrhenius equation, K = AeEa/RT

    From rate equation given in question

    Hence (C) is correct answer.   

     

  • Question 6/10
    4 / -1

    The correct IUPAC name of compound given below is 

  • Question 7/10
    4 / -1

    Directions For Questions

    ...view full instructions

    The work function of photosensitive surface. 

    Solutions

     

  • Question 8/10
    4 / -1

    5.6 litre of an unknown gas at NTP requires 12.5 calorie to raise its temperature by 10oC at constant volume. 

    Solutions

     

  • Question 9/10
    4 / -1

    The value of (PVm)P→0 of a real gas is independent of the nature of gas because

    Solutions

    At very low pressure the molar volume of gas is very high therefore; Vm >>>b , and molecular attraction are also negligible. Thus gas behaves as an ideal gas.  

    Hence (A) is correct answer. 

     

  • Question 10/10
    4 / -1

    Which of the following oxide cannot be reduced by carbon reduction?

    Solutions

    MnO2 and Cr2O3 are reduced by aluminum.
