Q1. In the rate equation, when the conc. of reactants is unity then rate is equal to
*
1 point
average rate constant
None of above
instantaneous rate constant
specific rate constant
Q2. The rate of reaction between two specific time intervals is called
*
1 point
rate
ordinary rate
specific rate
instantaneous rate
Q3. Instantaneous rate of a chemical reaction is
*
1 point
rate of reaction at a given instant of time
rate of reaction between two specific time intervals
rate of reaction at the end
rate of reaction in the beginning
Q4. At the beginning the decrease in the conc. of reactants is
*
1 point
Rapid
Moderate
None
Slow
Q5. The rate of reaction depends upon the
*
1 point
Force
Volume
Pressure
Concentration of reactant
Q6. Which one of the following statements for the order of a reaction is incorrect ?
*
1 point
Order can be determined only experimentally.
Order is not influenced by stoichiometric coefficient of the reactants.
Order of reaction is always whole number.
Order of reaction is sum of power to the concentration terms of reactants to express the rate of reaction.
Q7. The rate of reaction for 2NO + Cl2 = 2NOCl is given by, Rate = K [NO]^2.[Cl], The value of the rate constant can be increased by
*
1 point
increasing the temperature.
increasing the concentration of the Cl2
increasing the concentration of NO.
doing all of the above
Q8. Order of reaction can be
*
1 point
Zero
Fractional, Whole Number or Zero
Fractional
Whole number
Q9. Units of rate constant of first and zero order reactions in terms of molarity M unit are respectively
*
1 point
sec-1, Msec-1
sec-1, M-1
M-1, sec-2
M-1sec-1, sec-1
Q10. A reaction involving two different reactants can never be
*
1 point
unimolecular reaction
first order reaction
second order reaction
bimolecular reaction
