Consider the following reversible reaction. what is the equilibrium constant expression for the given system?

The question is incomplete. Complete question is attached below
..........................................................................................................................

 
Equilibrium constant (K) is defined as the ratio of concentration of product to concentration of reactant.

For the reaction:  2H2O(g)    ↔     2H2(g)      +       O2(g)

Equlibrium constant = 

[ ] bracket in above expression indicates concentration.

  

Charles's law

Explanation:

Charles' law gives a relationship between volume and absolute temperature at constant pressure. It's thus, states that the volume of a fixed mass of gas is directly proportional to its absolute temperature provided the pressure remains constant. Mathematically,

V & T

V = KT

K = V/ T

V1/T1 = V2/T2

Where

V1 is initial volume.

V2 is the final volume.

T1 is the initial temperature in Kelvin

T2 is the final temperature in Kelvin.
