Vedclass · Answer

(C) The average molecular speed $(v_{avg})$ is given by the formula: $v_{avg} = \sqrt{\frac{8RT}{\pi M}}$.This shows that $v_{avg} \propto \sqrt{\frac{T}{M}}$.Comparing the ratios of $\frac{T}{M}$ for each gas:$A: \frac{500}{32} = 15.625$$B: \frac{400}{44} \approx 9.09$$C: \frac{200}{4} = 50.0$$D: \frac{300}{17} \approx 17.65$Since the ratio $\frac{T}{M}$ is highest for $He$ $(50.0)$,it will have the greatest average speed.
