True because it actually formed I know
Answer:
B
Explanation:
Mass=concentration × volume
Therefore, concentration = mass/volume
C=6/2
C=3
Answer:
D) 2 NOCl(g) ⇄ 2 NO(g) + Cl₂(g); Kp = 1.7 × 10⁻²
Explanation:
In order to compare the degree of decomposition of these reactions, we have to compare the equilibrium constant Kp. Kp is equal to the partial pressure of the products raised to their stoichiometric coefficients divided by the partial pressure of the reactants raised to their stoichiometric coefficients. The higher the Kp, the more products and fewer reactants at equilibrium. Among these reactions, D is the one that has the highest Kp, therefore the one experiencing the largest degree of decomposition.
In the reaction NH3(g) +Cl2(g) --> NH4Cl(s) which occurs at 298 K, the delta S is negative because the reaction occurred <span>spontaneously and the product is less random than the reactants. Since the product is solid and the reactants are gases. </span>
