The reaction   \[CaC{{O}_{3}}\left( s \right)\rightleftharpoons CaO\left( s \right)+C{{O}_{2}}\left( g \right)\] is taking place in such a way that the vapour pressure of \[C{{O}_{2}}\] is equal to atmospheric pressure therefore, which of the following is not correct

A)  \[\Delta {{G}^{o}}=0\]

B)  \[{{K}_{P}}=1\]

C) \[\Delta G=0\]

D) \[\Delta H=0\]
