Question
For the reaction 2A + B → C, rate of disappearance of A 0.076 mol s –1.
- What is the rate of formation of C?
- What is the rate of consumption of B?
- What is the rate of the overall reaction?
Solution
Given: Rate of disappearance of A = `- ("d"["A"])/"dt"` = 0.076 mol s-1
To find:
- Rate of formation of C
- Rate of consumption of B
- 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
- Rate of formation of C= 0.038 mol s-1
- Rate of consumption of B = 0.038 mol s-1
- Rate of the overall reaction = 0.038 mol s-1
