Which one is not correct mathematical equation for Dalton's Law of partial pressure? Here P = total pressure of gaseous mixture
Options
- AP = n 1 RT V + n 2 RT V + n 3 RT V
- BP i = X i P , where P i = partial pressure of i th gas X i = mole fraction i th gas in gaseous mixture
- CP i = X i P i o , where X i = mole fraction of i th gas in gaseous mixture P i o = pressure of i th gas in pur
- DP = P 1 + P 2 + P 3
Correct answer
C. P i = X i P i o , where X i = mole fraction of i th gas in gaseous mixture P i o = pressure of i th gas in pur
Step-by-step solution
Dalton’s law of partial pressures is a gas law which states that the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures exerted by each individual gas in the mixture. P = P 1 + P 2 + P 3 P 1 ,   P 2   and   P 3 are the partial pressures and P is the total pressure. According to ideal gas equation P 1 = n 1 RT V ,   P 2 = n 2 RT V   and   P 3 = n 3 RT V Partial pressure of the individual gas can be expressed as follows, P i = X i P , P is tot
