(a)

Interpretation Introduction

Interpretation:

The rate constant of the given reaction has to be calculated.

Concept introduction:

Half-life: The time required for half of a reactant to be consumed in a reaction is said to be half-life.

  • Half-life of a reaction is represented by the symbol as t12
  • Half-life is discovered by Ernest Rutherford's in 1907 from the original term half-life period.
  • The half-life period is then shortened as half-life in early 1950s.

Arrhenius equation:

  • Arrhenius equation is a formula that represents the temperature dependence of reaction rates
  • The Arrhenius equation has to be represented as follows

k=AeEa/RT

  • Ea represents the activation energy and it’s unit is kJ/mol
  • R represents the universal gas constant and it has the value of 8.314 J/K.mol
  • T represents the absolute temperature
  • A represents the frequency factor or collision frequency
  • e represents the base of natural logarithm
  •  Arrhenius equation equation was proposed by Svante Arrhenius in 1889.
  • The activation energy for the given decomposition can be calculated from the modified Arrhenius equation.

lnk1k2=EaR[1T21T1]

Reaction: Substances which are mutually involved each other in a chemical process and changed into different substances.
