Answer:
The forward reaction will be favored.
Explanation:
The reaction is:
As per equation (equilibrium equation), there are two moles of gaseous molecules on product side and three moles of reactant side.
a) If we increase pressure, the volume will decrease.
b) Due to decrease in volume, the moles per unit volume will increase.
c) In order to attain equilibrium again, the system will shift in the direction where it can nullify this effect [Le Chatelier's principle]
d) This can be done, if system moves in the direction where number of moles of gaseous molecules are less, which is product side.
e) Thus forward reaction will be favored.
The alcohol concentration of the mixed solution is 20%
Simplification :
Based on the given condition, formulate :
35% ×0.40 + 0.6 ×10% ÷{ 0.4+0.6}
Calculate the product :
Calculate the sum or difference :
Any fraction with denominator 1 is equal to numerator : 0.2
Multiply a number to both numerator, denominator : 0.2 ×
Calculate the product or quotient :
A fraction with denominator equals to 100 to a percentage 20%.
How do you find the concentration of a mixed solution?
In general when your are mixing two different concentrations together first calculate number of moles for each solution (n=CV ,V-in liter) then add them together it will be total moles,then concentration of mixture will be = total moles / total volume(liter).
