QAIPM-2000-Ch-2982: NEET 2000 Chemistry - Class 11 AIPM-2000-Ch-2982 Solution: Equilibrium constant \(K_p\) for following reaction \(MgCO_3(s) …

Equilibrium constant KpK_p for following reaction MgCO3(s)⇌MgO(s)+CO2(g)MgCO_3(s)\rightleftharpoons MgO(s)+CO_2(g)

Multiple Choice Options

  • A Kp=PCO2K_p=P_{CO_2}
  • B Kp=PCO2⋅PMgCO3PMgOK_p=\frac{P_{CO_2}\cdot P_{MgCO_3}}{P_{MgO}}
  • C Kp=PCO2+PMgOPMgCO3K_p=\frac{P_{CO_2}+P_{MgO}}{P_{MgCO_3}}
  • D Kp=PMgCO3PCO2+PMgOK_p=\frac{P_{MgCO_3}}{P_{CO_2}+P_{MgO}}

Step-by-Step Verified Solution

K p = P CO 2 As solids do not exert pressure, so their partial pressure is taken as unity.
