# Two separate rigid containers of equal volume contain gas samples at identical temperatures of \(298 \text{ K}\). Container 1 contains \(\text{He(g)}\) and Container 2 contains \(\text{SO}_2\text{(g)}\). Which of the following correctly compares the average kinetic energy of the gas molecules and the rate of effusion of the gas in Container 1 relative to Container 2?

Two separate rigid containers of equal volume contain gas samples at identical temperatures of \(298 \text{ K}\). Container 1 contains \(\text{He(g)}\) and Container 2 contains \(\text{SO}_2\text{(g)}\). Which of the following correctly compares the average kinetic energy of the gas molecules and the rate of effusion of the gas in Container 1 relative to Container 2?

- **A.** The average kinetic energy of \(\text{He(g)}\) is equal to that of \(\text{SO}_2\text{(g)}\), and \(\text{He(g)}\) has a greater rate of effusion than \(\text{SO}_2\text{(g)}\).
- **B.** The average kinetic energy of \(\text{He(g)}\) is greater than that of \(\text{SO}_2\text{(g)}\), and \(\text{He(g)}\) has a greater rate of effusion than \(\text{SO}_2\text{(g)}\).
- **C.** The average kinetic energy of \(\text{He(g)}\) is equal to that of \(\text{SO}_2\text{(g)}\), and \(\text{He(g)}\) has a smaller rate of effusion than \(\text{SO}_2\text{(g)}\).
- **D.** The average kinetic energy of \(\text{He(g)}\) is less than that of \(\text{SO}_2\text{(g)}\), and \(\text{He(g)}\) has a smaller rate of effusion than \(\text{SO}_2\text{(g)}\).
