Question

at certain temperature and total pressure of 1 atm A2 vapours contains 20% by volume of A atoms A2(g)→2A(g) the kp of the reaction is

Comments

Thank you sir

Answer 1

The K_p of the reaction is 5 x 10³ 

Explanation:

Total Pressure,P = 1atm = 10⁵ Pa
As 20 % molecules are A atoms 80% are A₂ molecules.
Partial pressure of A(g), p_A = 0.2 x 10⁵ Pa
Partial pressure of A₂ (g), p_A2 =0.8 x 10⁵ Pa
