उत्तर

Given: Rate of disappearance of A = `- ("d"["A"])/"dt"` = 0.076 mol s-1

To find:

  1. Rate of formation of C
  2. Rate of consumption of B
  3. Rate of the overall reaction

Calculation:

Rate of reaction = `- 1/2 ("d"["A"])/"dt" = - ("d"["B"])/"dt" = ("d"["C"])/"dt"`

Rate of formation of C = `("d"["C"])/"dt" = - 1/2 ("d"["A"])/"dt"`

`= 1/2 xx 0.076` mol s-1

= 0.038 mol s-1

Rate of consumption of B = `- ("d"["B"])/"dt" = - 1/2 ("d"["A"])/"dt"`

`= 1/2 xx 0.076` mol s-1 

= 0.038 mol s-1 

Rate of reaction = `("d"["C"])/"dt"` = 0.038 mol s-1 

  1. Rate of formation of C= 0.038 mol s-1 
  2. Rate of consumption of B = 0.038 mol s-1 
  3. Rate of the overall reaction = 0.038 mol s-1
