Answer: The vapor pressure of the solution at 
is 29.86 mm Hg
Explanation:
As the relative lowering of vapor pressure is directly proportional to the amount of dissolved solute.
The formula for relative lowering of vapor pressure will be,
where,
= relative lowering in vapor pressure
i = Van'T Hoff factor = 1 (for non electrolytes)
= mole fraction of solute
=
Given : 9 moles of 
are dissolved in 50 L or 50000 ml of water
mass of water = 
moles of solvent (water) = 
Total moles = moles of solute + moles of solvent = 9 mol + 2778 mol = 2787
= mole fraction of solute
=
Thus the vapor pressure of the solution at is 29.86 mm Hg
Answer:
D) Rate = K [NO2][Cl2]
Explanation:
2 NO2 + Cl2 → 2 NO2Cl (overall reaction)
NO2 + Cl2 → NO2Cl + Cl (slow)
NO2 + Cl → NO2Cl (fast)
The rate-determining step is the slowest step in a reaction mechanism. Because it is the slowest, it determines the rate of the overall reaction.
Rate of reaction is typically given as;
Rate = K [Reactants]
In the slow step i the reaction mechanism, the reactants are; NO2 and Cl2. Since both are not intermediates, there is no need for further working out.
Rate = K [NO2][Cl2]
Convert 50mL to liters by dividing it by 1000 to get your liters value which should be 0.05 L
Now your formula is .20 = x/0.05
Solve for x to get your mol value and you should get 0.01 mol
