Which of the following is correct?

Correct answer: B. In some cases molecularity of a reaction is the same as order of reaction

  • A. Molecularity of a reaction is same as the order of reaction
  • B. In some cases molecularity of a reaction is the same as order of reaction
  • C. Molecularity of a reaction is more than order of reaction
  • D. All are correct

Explanation

Molecularity of a reaction is sometimes same as the order of reaction, because order of reaction is experimentally derived. It is not necessary that molecularity is always same sa that of order of reaction.

About Chemical Equilibrium

Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.

For a certain chemical reaction, the slope of the plot was determined and plotted against the concentration (a-x)2 and a straight line was obtained. It indicates that the reaction is of:

Consider the following general reaction: IA+IB → products. Rate of this reaction is expressed as: Rate = K[A]1[B]1 The correct order of reaction and molecularity is:

The unit of 1st order rate constant is:

A catalyst is more effective when it is in the finely divided state because:

Change in concentration of a reactant is plotted against time and the slope dx/dt determined. The values of dx/dt are plotted against (a-x)2 and a straight line is obtained. It may be concluded that the reaction is:
