Answer #1

Ans :- Option (a) i.e. It is pressure dependent .

Explanation :-

Equilibrium constant only depends upon temperature. I do not depends upon change in pressure, concentration, catalyst and addition of inert gases.

It is define as the "ratio of product of the molar concentration of products to the product of the product of molar concentration of reactants raised to the power of stoichiometric coefficient with respect to each reagent".

Also, It is the ratio of the rate of the forward reaction (rf) over the rate of the reverse reaction (rb).

Hence, option (a) is the correct answer.

For a general chemical equation A+B⇌C+D the equilibrium constant can be expressed as a ratio of the concentrations: Kc=[C][D]/[A][B] If this is an elementary chemical reaction, then there is a single forward rate and a single reverse rate for this reaction, which can be written as follows: forward rate=kf[A][B] reverse rate=kr[C][D] where kf and kr are the forward and reverse rate constants, respectively. When equilibrium is reached, the forward and reverse rates are equal: kf[A][B]=kr[C][D] Thus, the rate constants are...
