Saturated fatty acids lack double bonds between the individual carbon atoms, while in unsaturated fatty acids there is at least one double bond in the fatty acid chain. Saturated fats tend to be solid at room temperature and from animal sources, while unsaturated fats are usually liquid and from plant sources.
K(eq) = concentration of products/concentration of reactant = [Cu+2] / [Ag+]^2 Activity of pure solid and liquid is taken as 1. Hence last option is correct. Hope this helps, have a great day ahead! I hope this helps you alot :) :) :0
