1. Equilibrium expressions for the given balanced equations can be given as follows:
For each of the statements given, correct answer is:
c. The rates of the forward and reverse reactions are equal
From the following the one that causes a change in the value of Keq is:
a. increasing temperature
Because number of moles on reactant side and product side is same, so change in pressure will not affect Keq. The reaction is at equilibrium, so even we increase the reactant concentration, it will not affect Keq.
