Calculate the equilibrium constant Kp for this reaction, given the following information (at 299 K ): 2NO(g)+Br2(g)⇌2NOBr(g)Kc=2
Travka [436]

Answer:

2NO_{(g)}+Br_2_{(g)}\rightleftharpoons2NOBr_{(g)} , Kp = 0.08967

2NO_{(g)}\rightleftharpoons N_2_{(g)}+O_2_{(g)} , Kp = 2.3×10³⁰

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:

2NO_{(g)}+Br_2_{(g)}\rightleftharpoons2NOBr_{(g)}

Given: Kc = 2.2

Temperature = 299 K

R = 0.082057 L atm.mol⁻¹K⁻¹

Δn = (2)-(2+1) = -1

Thus, Kp is:

K_p= 2.2\times (0.082057\times 299)^{-1}

<u>Kp = 0.08967 </u>

For the second equilibrium reaction:

2NO_{(g)}\rightleftharpoons N_2_{(g)}+O_2_{(g)}

Given: Kc = 2.3×10³⁰

Temperature = 299 K

R = 0.082057 L atm.mol⁻¹K⁻¹

Δn = (2)-(2) = 0

Thus, Kp is:

K_p= 2.2\times (0.082057\times 299)^{0}

<u>Kp =  2.3×10³⁰</u>
