Question

The 1 mol of an Ideal das A with 300 mm of Hg separated by 2 mol of another ideal gas B with 300 mm of Hg in a closed container at the same temperature. If the separator is removed then total pressure is

Answer 1

Given-

P₁=P₂

n₁=1 mol

n₂=2 mol

P₁V₁=n₁RT            ;                P₂V₂=n₂RT

V₁=n₁RT/P₁          ;                 V₂=n₂RT/P₂

P=P₁V₁+P₂V₂/V₁+V₂            

P=  n₁RT+n₂RT / [n₁RT/P₁]  + [n₂RT/P₂]

P=n₁RT+n₂RT/ [n₁RT+n₂RT] /P₁

P=P₁

If separtors removed then total  pressure is 300mm of Hg.
