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

0

Step-by-step explanation:

The relation between Kp and Kc is given below:

`K_p= K_c* (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* * (RT)^(0)`

`K_p= Kc`
