Which of the following laws concerning gases is misstated? a. in a mixture of gases, the total pressure of the gases equals the sum of the individual pressures of each gas. b. at fixed temperature and pressure, the volume of a gas is inversely proportional to the number of moles of that gas. c. at fixed pressure, the volume of a gas is directly proportional to its temperature in kelvin. d. at fixed temperature, the volume of a gas is inversely proportional to its pressure. e. the average translational kinetic energy of the molecules of a gas is directly proportional to the temperature in kelvin.

b. At fixed temperature and pressure, the volume of a gas is inversely proportional to the number of moles of that gas.

Explanation:

Statement b is wrong.

We can prove it by looking at the ideal gas equation:

where

p is the gas pressure

V is the gas volume

n is the number of moles of the gas

R is the gas constant

T is the absolute temperature of the gas

If we have a gas at fixed temperature T and fixed pressure p, then we see that the relationship becomes

which means that the volume is directly proportional to the number of moles of the gas: so, the statement is wrong.

your answer is yx
