Answer: (a) The reaction mixture will proceed toward products.
Explanation:
Equilibrium constant is defined as the ratio of pressure of products to the pressure of reactants each raised to the power their stoichiometric ratios. It is expressed as
K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
For the given chemical reaction:
The expression for is written as:
Thus as , the reaction will shift towards the right i.e. towards the product side.
The molecular formula of the given compound is also known as Carbonic acid.
The simplest whole-number ratio of the various atoms in a compound is represented by an empirical formula.
The precise number of various atom types present in a compound's molecule is indicated by the molecular formula.
Given that,
H = 3.3%
C = 19.3%
O = 77.4%
No. of moles of H = 3.3/1
No. of moles of H = 3.3
No. of moles of C = 19.3 / 12
No. of moles of C = 1.60
No. of moles of O = 77.4/16
No. of moles of O = 4.83
Therefore, the ratio of the atoms of C, H and O = 3.3 : 1.60 : 4.83
Divide by smallest value which you get =3.3 / 1.60 : 1.60 / 1.60 : 4.83 / 1.60
The ratio of the atoms of C, H and O = 2 : 1 : 3
So, the empirical formula is
Let the molecular formula is
Then, molar mass
Molar mass = 62n
As the question, 62 n = 60
n = 0.96 or n = 1 (rounded off to nearest ones)
So, the molecular formula is i.e., the compound is Carbonic acid.
