Which one of the following graphs is not correct for ideal gas?

JEE Main 2020 (Online) 2nd September Morning Slot Chemistry - Gaseous State Question 37 English
d = Density, P = Pressure, T = Temperature

Multiple Choice Options

  • A II
  • B III
  • C I
  • D IV

Step-by-Step Verified Solution

For ideal gas,

PM = dRT [As V = Md{M \over d} ]

⇒\Rightarrow d = PMRT{{PM} \over {RT}}

∴\therefore d ∝\propto 1T{1 \over T} ⇒\Rightarrow d v/s 1T{1 \over T} graph is Straight line.

d v/s T ⇒\Rightarrow graph is Hyperbolic.

As d ∝\propto p

∴\therefore d v/s p graph is Straight line.
