Problem

A reaction C ⇌ D is monitored, and the following qualitative information is obtained from a rate-versus-time graph: • 0 – 20 s: rate_forward > rate_reverse • 20 – 35 s: rate_forward = rate_reverse • 35 – 55 s: rate_reverse > rate_forward During which of these three intervals does the concentration of products decrease?
