Explain why pure liquids and solids can be ignored while writing the equilibrium constant expression?

Write any two characteristics of equilibrium constant.

The reaction cis- X underset(k_(b))⇌overset(k_(f)) trans-X is first order in both directions. At 25^(@) C, the equilibrium constant is 0.10 and the rate constant k_(f) = 3 xx 10^(-4) s^(-1) . In an experiment starting with the pure cis-form, how long would it take for half of the equilibrium amount of the trans-isomer to be formed?

write whether the following statement is true or false. " high value of equilibrium constant suggest high concentration of the reactants in the equilibrium mixture"

During a class room discussing a student is of the view that value of equilibrium constant can be influenced by catalyst. Do you agree with the statement?

Assume that the reaction given below is at equilibrium. PCl_(5(g)) harr PCl_(3(g)) + Cl_(2(g)) , DeltaH = 124.0 Kjmol^-1 . Explain, how the following changes influence this equilibrium. Addition of neon gas at constant volume.

Why are amorphous solids are considered as super cooled liquids?

Explain why CuSO_4 is blue while ZnSO_4 is colourless.
