Question

If, $K_p=K_c\times {\left[RT\right]}^{\Delta n}$, for the reaction ; $2C{O}_2\left(g\right)+2CaC{O}_3\left(s\right)\rightleftharpoons 2Ca{C}_2\left(s\right)+5O_2\left(g\right)$; $\Delta n$ is equal to :

Answer 1

$\Delta n=5-2=3$

Here, $\Delta n$ is the difference in the number of moles of gaseous reactants and products.
