Question

A system of sulfur dioxide (SO2) gas has a pressure of 4.24 × 104 Pa and a temperature of 27°C. The molar mass of SO2 is 64.07 g/mol. Treat this as an ideal gas. (a) Calculate the density of the gas (in kg/m3). (b) What is the rms speed of the SO2 molecules? (c) What is the average translational kinetic energy per molecule? (d) If the gas undergoes an isochoric process in which the pressure of the gas decreases to half, will the rms speed of the SO2 molecules remain the same or change? If the rms speed remains the same, explain why. If the rms speed changes, calculate the new value.

Step 1

Given: Pressure (\(P\)) = 4.24 × 10^4 Pa Temperature (\(T\)) = 27°C = 300 K Molar mass of SO2 = 64.07 g/mol First, calculate the number of moles (\(n\)): \(n = \frac{PV}{RT} = \frac{(4.24 \times 10^4 \, \text{Pa}) \times V}{(8.31 \, \text{J/mol K} \times 300 \, Show more…
