Question

Among the following gases for how many gases Z>1 at any pressure 2 2 2 4 2 2 6 2 H H e S O C O C H N C H O

Answer 1

ANSWER

COMPRESSIBILITY FACTOR Z = 1+1/V(b-a/RT)

or

Z = PV/nRT

if we plot curve for different gases then

at low pressure certain gases have z <1 and some have z>1

for N2 and He it is always >1

see figure

mark me as brainliest
