Question

The rate of effusion of Br_2(g) compared to Cl_2(g), at the same temperature. would be greater less the same impossible to predict The average kinetic energy of Br_2(g) compared to Cl_2(g), at the same temperature, would be greater less the same Impossible to predict The root mean square speed of Br_2(g) compared to Cl_2(g). at the same temperature, would be greater less the same impossible to predict A 0.05 M aqueous sodium bromide solution has an osmotic pressure of 2.50 atm. At the same temperature, a 0.05 M aluminum chloride solution would have an osmotic pressure of 1.68 atm 2.50 atm 3.75 atm 5.00 atm The specific heat of water is 4.18 J/g degree C. When equal masses of zinc at 100 degree C and water at 20 degree C are combined in a calorimeter, the final temperature is 23 degree C. Compared to water, the specific heat of zinc is less greater the same Impossible to predict In 0.10 M Ba(NO_3)_2 the [NO_3^-]is 0.10 M 0.20 M 0.30 M

Explanation / Answer

rate of effusion, r is inversely proportional to molecular weight of the given gas, M.
Greater the M, lesser is the r.
MBr2 > MCl2
rBr2 < rCl2

B) less
