20) the species which is formed in one step and is consumed in some other step is called as intermediate
so in the given reaction BrO is the intermediate
21) Kc for the reaction will be
Kc = [H2] [I2] / [HI]2
Kc = 0.27 X 0.6 / (0.85)^1/2 = 0.224 = 0.22
22) We know that
Kp = Kc (RT)Δn
Where
Δn = number of moles of gaseous products - number of moles of gaseous reactants
Here Δn = 3-2 =1
R= gas constant= 0.0821 L atm /mol K
T= temperature = 400 C = 400 +273 K = 673K
Kp = 2.1 X 10^-2 (0.0821 X 673) = 1.160 = 1.2
