Homework Answers
Average sped of gas molecules are given by the equation, Cav = (8RT/pi* M)1/2. Where R= universal gas constant, T= temperature in kelvin, M= molecular weight of the gas. So at a fixed temperature for different gases average speed is inversely proportional to the square root of M. Molecular weight of carbon monoxide gas is 28 and that of sulfur dioxide is 64. So from the relation, we can say that the average speed of carbon monoxide will be greater. The average kinetic energy of a gas molecule is equal to (3/2)*kT, where k= Boltzmann constant and T= temperature of the gas in kelvin. Average kinetic energy is a function of temperature only, so for different gases, kinetic energy will be the same at a fixed temperature. The given statement is true.
