What is the average rate of reaction when change in concentration of product is 0.05 M in 20 seconds?

Options

  1. A0.0025 M s ⁻¹
  2. B0.05 M s ⁻¹
  3. C1.0 M s ⁻¹
  4. D4 0 M s ⁻¹

Correct answer

A. 0.0025 M s ⁻¹

Step-by-step solution

Average Rate of Reaction The average rate is defined as [ Product ] t for a product's concentration change over time. Given [ Product ] = 0.05 M and t = 20 s , we compute: Average Rate = 0.05 20 = 0.0025 M s ⁻¹ . This matches option A.
