As we know according to charles law volume is directly proportional to temperature at constant pressure. When temperature is increased the kinetic energy of molecules increase as a result of which number of Collison with container and other molecules also increases.
So the volume increase as a result of increase in collisons
So D) is correct

A certain temperature and volume would you expect the pressure
of a given number of moles of KR or CCL4 to deviate more from ideal
behavior? why?
O O O CCI, because it occupies a larger volume and has smaller dispersion forces between molecules. CCl4 because it occupies a smaller volume and has greater dispersion forces between molecules. CCl4 because it occupies a larger volume and has greater dispersion forces between molecules. Kr because it occupies a smaller volume and...
