For the reaction 2 H 2 O ( g ) − ⇀ ↽ − 2 H 2 ( g ) + O 2 ( g ) the equilibrium concentrations were found to be [ H 2 O ] = 0.250 M , [ H 2 ] = 0.330 M , and [ O 2 ] = 0.800 M . What is the equilibrium constant for this reaction?

The equilibrium constant for the given reaction is 4.224

Explanation:

We are given:

Equilibrium concentration of water = 0.250 M

Equilibrium concentration of hydrogen gas = 0.330 M

Equilibrium concentration of oxygen gas = 0.800 M

For the given chemical reaction:

The expression of for above reaction follows:

Putting values in above expression, we get:

Hence, the equilibrium constant for the given reaction is 4.224

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.
