400 mL of gas is contained at 300 mmHg and 0 °C. What will its volume be at 140 mmHg and 100 °C? 0°C 100°C
PIT_PIT [208]

Answer:

1171.12 mL

Explanation:

Using the combined gas law equation;

P1V1/T1 = P2V2/T2

Where;

P1 = initial pressure (mmHg)

P2 = final pressure (mmHg)

V1 = initial volume (milliliters)

V2 = final volume (milliliters)

T1 = initial temperature (Kelvin)

T2 = final temperature (Kelvin)

According to the information provided in this question:

P1 = 300 mmHg

P2 = 140 mmHg

V1 = 400 mL

V2 = ?

T1 = 0°C = 273K

T2 = 100°C = 100 + 273 = 373K

Using P1V1/T1 = P2V2/T2

300 × 400/273 = 140 × V2/373

120000/273 = 140V2/373

120000 × 373 = 273 × 140V2

44760000 = 38220V2

V2 = 44760000 ÷ 38220

V2 = 1171.115

The new volume is 1171.12 mL

Which of the following is true for a system whose equilibrium constant is much greater than one?
vladimir2022 [97]

Answer:

A) The reaction mixture contains mostly products at equilibrium  

Explanation:

For the general reaction

Reactants ⇌ Products

The equilibrium constant is

K_{\text{eq}} = \dfrac{\text{[Products]}}{\text{[Reactants]}}

Thus, if K is large, the concentration of products is greater than that of reactants.

The reaction mixture will contain mostly products at equilibrium.

C) and E) are wrong. The equilibrium constant gives us information only on the position of equilibrium, not on how fast it is achieved.
