The equilibrium constant of reaction, usually denoted as K, is a unit of ratio. The ratio involves concentrations or partial pressures of products to reactants. But you also have to incorporate their stoichiometric coefficients in the reaction as their respective exponents. If K is in terms of concentration, only the substances in their aqueous state are the ones that are included only in the expression. If K is in terms of partial pressures, only the substances in gaseous states are the ones that are included only in the expression. For this problem, it would be in terms of partial pressures. To properly show you how it's done, consider this equilibrium reaction:
aA (g) + bB (g) ⇆ nN (g)
The equilibrium constant for this reaction is:
K = [N]ⁿ/[A]ᵃ[B]ᵇ
where the [] brackets denotes partial pressures of the substances
Particularly, for the reaction <span>a(g)⇌b(g), the K expression would be
</span>K = [B]/[A]
So, if K is less than one, that means that the numerator is less than the denominator. It follows that the partial pressure of reactant A is greater than product B. Since A is greater, then the more favorable direction would be the forward reaction. The δG°rxn would then be negative in value. So δG°rxn < 0.
To explain, δG°rxn is a criterion for spontaneity. If δG°rxn is negative, the reaction is spontaneous. If δG°rxn is positive, it is non-spontaneous. Since the favorable reaction is the forward reaction, it is spontaneous.
Answer:
If you want to calculate the number of moles of any compund, you should look for the molar mass. For LiF, its molar mass is 25,9 g/m So if 25,9 g are in one mol, the 317 in how many?. Then 12,2 is the number of moles of lithium fluoride produced.
Explanation:
To get the molar mass of a compound, you should know the mass at the Periodic Table, for Li 7,00 , for F 18,9
Of what lol. dndkdmsldksmsnsjdjdbdh
Answer:
0.8 mL
Explanation:
Use the formula M1V1 = M2V2.
Plug the values in.
5(V1) = 0.02(200)
5V1 = 4
V1 = 0.8 mL
Hope this is right, correct me if I'm wrong!
Answer:
Strong Acid
Explanation:
ph 1 to 7 acidic 7 is neutral and onwards till 14 is alkali so in this case its ph is 2 which is a strong acidic
