Question

What is Δn for the following equation in relating Kc to Kp?2 SO2(g) + O2(g) ↔ 2 SO3(g)23-2-11

Answer 1

-1

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:

`2SO_2_((g))+O_2_((g))\rightleftharpoons2SO_3_((g))`

Δn = (2)-(2+1) = -1

Thus, Kp is:

`K_p=  K_c* (RT)^(-1)`
