Answer:
Smaller; products; products
Explanation:
aA + bB ⇌ cC + dD
Answer:
3. a. I⁻
Explanation:
The charge of the ion is determined by which group (vertical on the periodic table) the element is in. Iodine is in the halogens and therefore is most likely to have a 1- charge.
Minerals determines the composition of a rock
The equilibrium constant of the reaction is 0.323.
Equilibrium constant:
It is expressed as the ratio of concentration of the products to the concentration of reactants. It is represented by K.
The relationship of K with G (Gibbs free energy) is expressed as:
G° = -RTlnK
Here R is the gas constant, T is the temperature.
Calculations:
Convert 25°C to K.
25°C = (25 + 273.15) K
= 298.15 K
Substitute the values in the above expression.
2.8 x 1000 J/mol = -8.314 J/mol.K x 298.15 K x ln(K)
lnK = 2800 J/mol/(-8.314 J/mol.K x 298.15 K)
lnK = -1.13
K = e^-1.13
= 0.323
