Interpretation Introduction

Interpretation:

The rate constant and half-life for the given radium decay and the activity after 500yr have to be determined.

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.
  • The formula which is used to calculate the half-life is t12=0.693k

Rate law: It is an equation that related to the rate of reaction to the concentrations or pressures of substrates (reactants).  It is also said to be as rate equation.
