A mixture of gases and are taken in a closed vessel containing charcoal. The graph that represents the correct behaviour of pressure with time is :
We know that,
Charcoal is an adsorbent and the gases H2, O2 and CO are adsorbates. These gases get adsorbed on charcoal and with time pressure decreases.
Hence, the option number (3) is correct.
5 g of Na2SO4 was dissolved in x g of H2O. The change in freezing point was found to be 3.820C. If Na2SO4 is 81.5% ionised, the value of x (K
