Sample questions
-
1.The half-life of a reaction is defined as the time in which:
- A.The concentration of a reactant is reduced to one half of its initial value
- B.The reaction reaches completion
- C.The rate constant becomes half
- D.The concentration of the product becomes equal to that of the reactant
-
2.For a chemical reaction, by what factor does the rate constant nearly change for a rise in temperature of 10 degrees? (NCERT, Temperature Dependence section)
- A.It is nearly doubled
- B.It is nearly halved
- C.It increases ten times
- D.It remains nearly unchanged
-
3.The order of a reaction is defined as:
- A.The sum of the powers of the concentration terms in the rate law expression
- B.The number of molecules in the balanced equation
- C.The number of reactants in the reaction
- D.The sum of the stoichiometric coefficients of products
-
4.A plot of ln k against 1/T according to the Arrhenius equation gives a straight line with slope equal to:
- A.-Ea/R
- B.-Ea/2.303R
- C.ln A
- D.-Ea/RT
-
5.For the reaction Hg(l) + Cl2(g) gives HgCl2(s), where all stoichiometric coefficients are one, the rate of disappearance of a reactant is:
- A.Equal to the rate of appearance of the product
- B.Twice the rate of appearance of the product
- C.Half the rate of appearance of the product
- D.Unrelated to the rate of appearance of the product
