Ka is acid dissociation constant.
The acid with smallest value of Ka is weakest.
Ka is smallest for HIO
So, HIO is weakest acid
Answer: B
10)
Kp is defined as pressure of product by pressure of reactant with each pressure term raised to power that is equal to its stoichiometric coefficient in balanced equation
Use:
Kp = p(NO)^2 * p(Cl2) / p(NOCl)^2
1.9*10^-2 = p(NO)^2 * 0.50 / 0.33^2
p(NO)^2 = 4.138*10^-3
p(NO) = 0.064 atm
