Answer 1

Answer:

1. Dynamic equilibrium is a equilibrium in which the rate of forward direction is equal to the rate of backward direction. It is represented by a right left arrow.

2) Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as $K_c$  

For the given chemical reaction:

$Fe^{3+}(aq)+SCN^-(aq)\rightleftharpoons [Fe(SCN)]^{2-}(aq)$

The expression for $K_c$ is written as:

$K_c=\frac{[[Fe(SCN)]^{2-}]}{[Fe^{3+}][SCN^-]}$

3) The value of $K_c$ is 1000 , which means the products are more favoured as compared to reactants and that the equilibrium lies more towards product side.
