Which of the following is true regarding Keq?

Chemistry
1 answer:
grandymaker [24]3 years ago
6 0

Answer:

option b is true

Explanation:

Since the equilibrium constant Kp is defined as the ratio of [products]/[reactants] ( option c is false) , then Kp units depends on the order of reaction of the reactants and the number of reactants and products involved ( option a is false).

for example if the concentration is expressed as M (molarity)

Keq= [A]/[B]*[C] then Kep has as units 1/M

Also t a specific temperature , the equilibrium constant represents the relationship between concentrations of reactants and products , and its fixed at constant temperature (option b is true).

A gas has a volume of 490. mL at a temperature of -35.0 degrees C. What volume would the gas occupy at 42.0 degrees Celsius? Ple
miskamm [114]

Answer:

648.5 mL

Explanation:

Here we will assume that the pressure of the gas is constant, since it is not given or specified.

Therefore, we can use Charle's law, which states that:

"For an ideal gas kept at constant pressure, the volume of the gas is proportional to its absolute temperature"

Mathematically:

\frac{V}{T}=const.

where

V is the volume of the gas

T is its absolute temperature

The equation can be rewritten as

\frac{V_1}{T_1}=\frac{V_2}{T_2}

where in this problem we have:

V_1=490 mL is the initial volume of the gas

T_1=-35.0^{\circ} + 273 = 238 K is the initial temperature

T_2=42.0^{\circ}+273=315 K is the final temperature

Solving for V2, we find the final volume of the gas:

V_2=\frac{V_1 T_2}{T_1}=\frac{(490)(315)}{238}=648.5 mL
