Question

The kinetic molecular theory predicts that pressure rises as the temperature of a gas increases, because: the average kinetic energy of the gas molecules decreases the gas molecules collide less frequently with the wall the gas molecules collide more frequently with the wall the gas molecules collide more frequently and more energetically with the wall the gas molecules collide more energetically with the wall Of the following gases, which will have the greatest rate of effusion at a given temperature? Ar NH_3 HBr CH_4 CO_2

Explanation / Answer

1. Option D

Since kinetic energy directly proportional to temperature, after increasing Temperature gas particle collide more frequent and energetically with wall.

2. Option D (CH4)

Since rate of effusion is inversely proportional to molar mass .lowest molar mass containing compound will have maximum effusion .
