Question

In the relation, $K_p = K_c (RT)^{\Delta n}$ the value of $\Delta n$ is

• A. number of moles of gaseous reactants $-$ number of moles of gaseous products in a balanced equation
• B. number of moles of gaseous products $-$ number of moles of gaseous reactants in a balanced equation
• C. number of moles of gaseous products $\times$ number of m oles of gaseous reactants in a balanced equation
• D. number of moles of gaseous reactants $+$ number of moles of gaseous products in balanced equation

Answer 1

Answer: (B)

number of moles of gaseous products $-$ number of moles of gaseous reactants in a balanced equation

Answer 2

$\Delta n_{g}=n_{g\left(p\right)}-n_{g\left(r\right)}$
