Answer:
Explanation:
For a chemical reaction, equilibrium is a state at which the rate of the forward reaction equals that of the reverse reaction. The equilibrium constant Keq is a parameter characteristic of this state which is expressed as a ratio of the concentration of the products to that of the reactants.
For a hypothetical reaction:
xA + yB ⇄ zC
The equilibrium constant is :
The given reaction involves the decomposition of H2O into H2 and O2
The equilibrium constant is expressed as :
Since Keq = 5.31*10^-10
Answer:
Pi = 0.25[P(TTL)/n(TTL)]
Explanation:
Let Total Pressure = P(TTL) and Total moles =n(TTL) => n(i)/n(TTL) = P(i)/P(TTL)
Given n(i) = 0.25 => Pi = 0.25[P(TTL)/n(TTL)]
