Question

Which of the following statements about equilibrium expressions and equilibrium constants are correct? Choose all that apply. Check all that apply. For chemical reactions in which all reactants and products are gases, K. can never be equal to K The equilibrium expression for a reaction involving only gases can be written in terms of either partial pressures or concentrations. A homogeneous equilibrium is one where all reactants and products are in the same physical state, When a chemical reaction is multiplied by a constant, the corresponding equilibrium expression is raised to the power of that constant.

Answer 1

Answer → for any general reaction, AB Equillibrian Coastant (K) can be written as, - Kafententration of Products 7 - concentration of Reactants So, for ea. no - k=f67 47 Now, lets multiply eqin 1 with a constant n, u get . AB - So, Equillibrum constant (ki for egin o home for those fogja {k=kh so, statement Ý is correct und WA --> B → Homogeneous equillibrum for systeme) has all reactants of products in some phase for physical Stated So statement } is correct .

lets take a general homogeneous reaction having reactants and products as gaser only. ----_AA_+bB GdD =3 where A, B are reactants; CD are Products: ab, esd are coefficients of A, B, C&D respectively low, equillibrium constant (k I in terms of Concentrations of gases involved is, er fetg]' forgs] - faces]a[Begi? Also, for ideal gases Pressure of a gas is proportional to concentration, at constant temperature. So, - Profa], PA -> Pattiat pressure of Ā Also, we know that ---- Pras = [ga]rt t from from ide ideal gas equation) Now, equitlibriem constant can also be written in terms of either partial pressures or concentrations as both are proportional to each other.
