At high temperature, the following reaction occurs
4CuO4CuO\left(s\right) ⇌ 2C{u}_{2}O(s)+O2(g)\left(s\right) + {O}_{2}\left(g\right)
Consider the following statements regarding reaction
1.1 . Kp=pO2{K}_{p} = {p}_{{O}_{2}}
2.2 . Kp{K}_{p} depends upon the amounts of CuO and Cu2OC{u}_{2}O
3.3 . Kp<<Kc{K}_{p} < < {K}_{c}
4.4 . Kp>Kc{K}_{p} > {K}_{c}
Of the statements

Options

  1. A1 and 2 are correct
  2. B1, 2 and 3 are correct
  3. C1 and 4 are correct
  4. D2 and 3 are correct

Correct answer

C. 1 and 4 are correct

Step-by-step solution

{K}_{p} = {p}_{{O}_{2}}iscorrect.<br/>[O2(g)]∝pO2is correct. <br/>\left[{O}_{2}\left(g\right)\right] ∝ {p}_{{O}_{2}}
Kp=Kc(RT)Δng{K}_{p} = {K}_{c} ( RT{)}^{\Delta{n}_{g}}
Δng=\Delta{n}_{g} = Number of mol gaseous (Products – Reactants)
Here Δng=1\Delta{n}_{g} = 1
So Kp>Kc{K}_{p} > {K}_{c}
