An equilibrium constant is not changed by a change in pressure.

True or False

True

Explanation:

Only temperature changes the value of the equilibrium constant.

For any system in equilibrium, the molar concentration of all the species on the right side are related to the molar concentration of the species on the left side by the equilibrium constant .

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
