  2. 2C(s) + O2(g) <------> 2CO(g)

  3. N2(g) + 3H2(g) <------> 2NH3(g)

  4. CaCO3(s) <------> CaO(s) + CO2(g)

A Correct answer
Explanation

The relation between Kp and Kc is given as Kp = Kc(RT)∆ng………………∆ng is the difference between the number of moles of gaseous products and reactants.For this reaction ∆ng is 0. Hence Kp = Kc. Hence this is the correct answer.
