Topic:

Reaction Kinetics

Question:

For third order reactions the half life is?

Options:

  • Independent of the initial concentration of the reactants
  • Inversely proportional to the initial concentration of the reactants
  • Inversely proportional to the square of the initial concentration of the reactants
  • Inversely proportional to the cube of the initial concentration of the reactant

Right Answer:

Inversely proportional to the square of the initial concentration of the reactants

Explanation:

For third order reactions, the rate of the reaction is inversely proportional to the square of the initial concentration of the reactants.

[t1/2] = 1.5/ka2

Topic:

Transition Elements

Question:

Binding energies of the transition elements are?

Options:

  • Weak
  • Strong
  • Very weak
  • Depends on the series

Right Answer:

Strong

Explanation:

Binding energies are high because apart from s-electrons of the outermost shell, the electrons of underlying half filled d-orbitals also participate in the binding energies. That is why transition elements are tough metals.

Topic:

Chemical Bonding

Question:

Which of the following is true about ionic compounds?

Options:

  • Directional nature
  • Non-Directional nature
  • Soluble in benzene
  • Slow reactions 

Right Answer:

Directional nature

Explanation:

Ionic compounds have electrostatic lines of forces between the oppositely charged ions which hold the atoms firm and thus these are non-directional in nature.

All other options are incorrect.
