Question

For a reaction R → p the concentration of reactant change from 0.03 m to 0.02 m in minute, calculate the average rate of the reaction using the unit of second.

Options

• 7.1 × 10^–6 ms^–1

• 1.25 × 10^–5 ms^–1

• 6.66 × 10^–6 ms^–1

• 4.25 × 10^–6 ms^–1

Answer 1

6.66 × 10^–6 ms^–1 

Explanation:

Average rate `(Δ[R])/(ΔL)`

= `((0.02 - 0.03)  m)/(25 xx 605)`

= 6.66 × 10^–6 ms^–1
