Write the concentration equilibrium constant expression for this reaction.

Chemistry
1 answer:
tankabanditka [31]3 years ago
3 0

Answer:

K = [Cu2^+] / [Ag^+]^2

Explanation:

The equilibrium expression written for a system in equilibrium must take into account the balanced equation for the reaction and the phases (solid, liquid, gas, or dissolved) of each species involved in the reaction.

aA + bB ⇆ cC + dD

Kc = [C]^c + [D]^d / [A]^a + [B]^b

"[ ]" - concentration of the species (moles per liter or molarity)

"a, b, c, d" - coefficients used to balance the equation

"c in Kc" - indicates that the value of K is determined using the concentrations of each species

There are two cases when a species is not shown in the equilibrium expression:  when it is a solid and when it is a pure liquid or solvent.

A sample of carbon dioxide gas occuples a volume of 2.5L at standard temperature and pressure (STP). What will be the volume of
MArishka [77]

Answer:

The correct answer is 5.0 L

Explanation:

STP are defined as T=273 K and P= 1 atm

By using the ideal gas equation, we can calculate the number of moles (n) of the gas at a volume V=2.5 L:

PV= nRT

⇒n= (PV)/(RT) =(1 atm x 2,5 L)/(0.082 L.atm/K.mol x 273 K)= 0.112 mol

For a sample of argon gas, with the same number of moles (0.112 mol) but twice the temperature (T = 273 K x 2= 546 K):

V= (nRT)/P = (0.112 mol x 0.082 L.atm/K.mol x 546 K)/1 atm = 5.0 L

That is consistent with the fact that when a gas is heated, it expanses. So, if the temperature increases twice, the volume also increases twice.
