Question

What is Δn for the following equation in relating Kc to Kp?SO3(g) + NO(g) ↔ SO2(g) + NO2(g)12-20-1

Answer 1

Answer:

0

Explanation:

The relation between Kp and Kc is given below:

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

Where,  

Kp is the pressure equilibrium constant

Kc is the molar equilibrium constant

R is gas constant

T is the temperature in Kelvins

Δn = (No. of moles of gaseous products)-(No. of moles of gaseous reactants)

For the first equilibrium reaction:

$SO_3_{(g)}+NO_{(g)}\rightleftharpoons SO_2_{(g)}+NO_2_{(g)}$

Δn = (2)-(2) = 0

Thus, Kp is:

$K_p= Kc\times \times (RT)^{0}$

$K_p= Kc$
