Question

A reaction follows the given concentration (M)-time graph. The rate for this reaction at 20 seconds will be

• A. $4\times {10}^{-3}M/s$
• B. $8\times {10}^{-2}M/s$
• C. $2\times {10}^{-2}M/s$
• D. $7\times {10}^{-3}M/s$

Answer 1

The correct option is D $7\times {10}^{-3}M/s$

$Rate=\frac{0.38}{50}=7\times {10}^{-3}M/s$
