Question 3 of 5

3. Question

Which of the following is/are always correct for a homogeneous gaseous equilibrium where \(K_c\) = Equilibrium constant (in terms of concentrations), and \(K_p\) = equilibrium constant,(in terms of pressure)?

\(K_c\) = \(K_p\)

\(K_c\) = \(K_p \times [RT]^{\Delta n}\)

\(K_p\) = \(K_c \times [RT]^{\Delta n}\)

\(K_c\) = \(K_p \times [RT]^{-\Delta n}\)

Correct

Incorrect
Question 4 of 5

4. Question

For the equilibrium\(\ce{PCl5(g) <=> PCl3(g) + Cl2(g)}\):

\(K_p\) = \(K_c \times [RT]\)

\(K_c\) = \(K_p \times [RT]\)

\(K_c\) = \(K_p \times [RT]^2\)

\(K_p\) = \(K_c \times [RT]^{2}\)

Correct

Incorrect
Question 5 of 5

5. Question

For the equilibrium, \(\ce{2NO(g) + Cl2(g) 2NOCl(g)}\)

\(K_p\) = \(K_c \times [RT]\)

\(K_c\) = \(K_p \times [RT]\)

\(K_c\) = \(K_p \times [RT]^2\)

\(K_p\) = \(K_c \times [RT]^{2}\)

Correct

Incorrect
