Help with this question please? And you can explain the principles of how to work it out?
Q) The most general form of an equilibrium constant is given by:
K = Π[concentration]u
where Π (‘pi’) refers to the product of all the concentration terms of both reactants (e.g. [A] and [B]) and their products (e.g. [C] and [D]). u (‘nu’) is the stoichiometric coefficient (positive for products and negative for reactants).
Write the equilibrium constant K for the general reaction:
aA + bB → cC + dD
where ‘A’ refers to a reactant A and a to its stoichiometric coefficient, ‘C’ refers to a product C and c to its stoichiometric coefficient, etc.
Give the expression of the natural logarithm of K.
a) ln(K) = [A]-a × [B]-b × [C]c × [D]d
b) ln(K) = - a ln [A] ×(- b ln [B]) × c ln [C] × d ln[D]
c) ln(K) = - ln [A]/a - ln [B]/b + ln [C]/c + ln[D]/d
d) ln(K) = - a ln [A] - b ln [B] + c ln [C] + d ln[D]
