i need help for the three questions

Write the expression for the equilibrium constant Kp for the following reaction. Enclose pressures in parentheses and do NOT write the chemical formula as a subscript. For example, enter (PNH3)2 as (PNH3)2. If either the numerator or denominator is 1 , please enter 1 2Cl2O(g)+3O2(g)4ClO2(g) Write the expression for the equilibrium constant Kp for the following reaction.
