No, because hydrogen isn’t brought out of the equation
I think the correct answer from the choices listed above is option B. When a substance changes from one phase to another, the average kinetic energy of the substance <span>changes since the molecules movements are changed as well. Hope this answers the question. Have a nice day.</span>
Answer:
0.595
Explanation:
Let's consider the decomposition of hydrogen chloride.
2 HCl(g) ⇄ H₂(g) + Cl₂(g)
The pressure equilibrium constant (Kp) is equal to the product of the partial pressure of the products raised to their stoichiometric coefficients divided by the product of the partial pressure of the reactants raised to their stoichiometric coefficients.
Kp = pH₂ × pCl₂ / pHCl²
Kp = 77.9 × 54.4 / 84.4²
Kp = 0.595
5.70 g ZrF4* (1 mol ZrF4/ 167.2 g ZrF4)= 0.0341 mol ZrF4.
The final answer is 0.0341 mol ZrF4~
