Answer:

Yes, it can.

Explanation:

The percentage yield is decreased if the reactants do not completely form the products. To make a given mass of product, a process with a low percentage yield requires more of the reactants than a process with high percentage yield.

The reaction 2 a → b c has a kc of 0.2. the reaction is commenced with initial concentrations [a] = 0.2 m, [b] = 0.2 m and [c] =
LuckyWell [14K]
Kc = [b]*[c]/([a]^2) = (0.2 M)^2/(0.2 M)^2 = 1.0
To achieve equilibrium, Kc must be equal to 0.2, therefore Kc must decrease, so the concentrations of b and c must decrease and the concentration of a must increase, meaning the reaction will proceed toward the formation of a.

A constant volume of oxygen is heated from 100°C to 155°C. The
dybincka [34]

Answer:

= 3.56 atm

Explanation:

Using Boyle's law which states that the volume of a given mass of gas is inversely proportional to the pressure and Charles law states the volume of a given mass of gas is directly proportional to the temperature.

P1/T1 = P2/T2

P1 = 3.1 atm, T1 = 100'C = 100+273 = 373K

T2 = 155'C = 155 + 273 = 428K

3.1/ 373 = P2 / 428

Cross multiply

373 × P2 = 3.1 × 428

373×P2 = 1326.8

Divide both sides by 373

P2 = 1326.8 ÷ 373

P2 = 3.56 atm

which of the following activities could cause liquid molecules to overcome intermolecular attractive forces and become gas molec
Anna [14]
The answer is C. increasing the temperature of the liquid.

Increasing the temperature of the liquid also means that you are providing energy to the liquid, which makes the molecules overcome intermolecular attractive forces, move more constantly, and become gas molecules.

Hope this would help~
