Question

A(aq) <=> 2B(aq)

Check all of the following statements that are true about this reaction. Assume you start with one mole of A and zero moles of B in 1 liter of solution. The reaction is then allowed to proceed until it reaches equilibrium.

None of these are true
If K << 1, then at equilibrium, there would be more A than B
If K << 1, then starting with equal amounts of A and B, the forward reaction will have a smaller rate than the reverse reaction
If at equilibrium there were 0.5 moles of A remaining, then the value of K = 1.
If K >> 1, then at equilibrium, there would be more B than A

Explanation / Answer

[A] = 1

[B] = 0

If K << 1, then at equilibrium, there would be more A than B TRUE
If K << 1, then starting with equal amounts of A and B, the forward reaction will have a smaller rate than the reverse reaction FALSE; rates has nothing to do with equilibrium
If at equilibrium there were 0.5 moles of A remaining, then the value of K = 1. TRUE
If K >> 1, then at equilibrium, there would be more B than A TRUE
