At STP, 0.50 mol H_(2) gas and 1.0 mol He gas – InterviewSolution

1.	At STP, 0.50 mol H_(2) gas and 1.0 mol He gas
Answer» Have equal AVERAGE KINETIC ENERGIES Have equal molecular speeds Occupy equal volumes Have equal EFFUSION rates Solution :For same TEMPERATURE kinetic energies of `H_(2)` & He molecule will be same because kinetic energy depends only on temperature.
