Question

Consider the reversible reaction, A+B⇌C+D. If the concentration of product C is decreased, the rate of the reverse reaction would ______________.

Group of answer choices

be unaffected

increase

decrease

Answer 1

Decrease or be unaffected. If only one answer choice is accepted, say that the rate would decrease

Step-by-step explanation:

The rates for the forward and backward reactions would be:

`Rf=k[A]^a[B]^b` forward (Rf = forward rate)
and

`Rb=k_(-1) [C]^c[D]^d` backwards (Rb = backward rate)

[A] would be the concentration of A, [B] would be the concentration of B, ect.
Since C decreases, the rate of the backwards reaction would decrease as long as c (lowercase!) is not 0. If c is 0, then the concentration of C would not affect the reaction rate. c is rarely 0, so the rate would probably decrease as the concentration of c decreases.
