Select the best answer for the question. 13. A reversible reaction has an equilibrium constant of 0.75. If the forward rate constant is 0.62 mol/L/s, what's the
reverse reaction rate constant?
A. 1.210
B. 0.827
O C. 0.910
D. 1.010

B

Explanation:

The rate constant is equal to forward rate divided by reverse rate.

K = f/r

-> r = f/K

0.62/0.75 = 0.8267

what are the statements

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
