MCQ
Which statement is wrong regarding osmotic pressure $(P), $ volume $  (V)$  and temperature $  (T)$
  • A
    $P \propto \frac{1}{V}$ if $T$ is constant
  • B
    $P \propto T$ if $V$ is constant
  • ✓
    $P \propto V$ if $T$ is constant
  • D
    $PV$is constant if $T$ is constant
✓

Answer

Correct option: C.
$P \propto V$ if $T$ is constant
c
$P = CRT =\frac{ n }{ V } RT$

At constant $T$,

$P \propto \frac{1}{ V }$
