Equilibrium Tes...

It accepts a proton. It is called as:

What is a buffer?

$${N}_{2}(g)+3{H}_{2}(g)\rightleftharpoons  2{NH}_{3}(g)+heat$$
Given the reaction shown above, which change will not shift the equilibrium position for the reaction?

What is the $${K}_{eq}$$ for the following reaction?
$${H}_{2}(g)+{I}_{2}(g)\rightleftharpoons  2HI(g)$$

Statement I: Water makes a good buffer.
Statement II: A good buffer will resist changes in pH.

Addition of water to this solution will not change $$[H_3 O^+]$$.

For each pair of chemicals below, the amounts shown are dissolved, together, in water to make 1.0 L of solution. Which mixture will form a buffer solution?

An increase in pressure in this reaction would:

If the $${K}_{eq}$$ for a reversible reaction is slightly less than $$1$$, which of the flowwoing statements is true?

$$P{Cl}_{3}(g)+{Cl}_{2}(g)\rightleftharpoons  P{Cl}_{5}(g)+energy$$
For the reaction above, what is the effect of increasing the pressure?
