Test: Law of Corresponding States - Chemistry MCQ

pressure and volume

pressure and temperature

volume and temperature

pressure, volume and temperature

it would be more convenient

the general shapes of the vapour dome and of the constant temperature lines on the p-v plane can be similar for all substances

their similarity can be exploited using dimensionless properties

all of the mentioned

the specific volumes of different gases at same pressure and temperature are different

the reduced volumes of different gases at same reduced pressure and reduced temperature are same

both of the mentioned

none of the mentioned

reduced pressure

reduced volume

reduced temperature

all of the mentioned

when reduced pressure is plotted as a function of reduced temperature and Z

when reduced temperature is plotted as a function of reduced pressure and Z

when Z is plotted as a function of reduced pressure and reduced temperature

none of the mentioned

reduced pressure and reduced temperature

reduced volume and reduced temperature

reduced volume and reduced pressure

reduced pressure and reduced temperature and reduced volume

at low temperature, three positive real roots exists

at critical temperature, the three real roots become equal

at high temperature, only one real root exists

all of the mentioned

the individual coefficients a,b,R for a particular gas have disappeared

it reduces the properties of all gases to one formula

it tells us that to what extent a real gas obeys van der Waals equation

all of the mentioned

zero
