In a unimolecular reaction with seven times as much starting material as product at equilibrium, what is the value of keq?

K_eq = 0.14

The chemical equation is  

A ⇌ B

The equilibrium constant expression is

K_eq = [B]/[A]

If [A] = 7[B]

K_eq = [B]/{7[B]}= 1/7 = 0.14

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
