ANSWER:
Solution 30P
Here, we have to find the highest partial pressure gas and partial pressure of D2.
Step 1 of 4
Dalton’s law of partial pressure:
The total pressure in a mixture of gases is the sum of the partial pressure of each gas.
Ptotal = P1 + P2 + P3+ ……….
Raoult’s law:
When two liquids that are completely soluble in one another are mixed together, the partial pressure of a component equal to its vapour pressure when pure at this temperature and its mole fraction in liquid.
PA = XA Ptotal
PA = Partial pressure of gas A
XA = Mole fraction of gas A
Ptotal = Vapor pressure of mixture.
