Question

The equilibrium constants for HCN and HAc are 4.0 × $10^{-10}$ and 1.9 × $10^{-5}$ mole/L respectively. Which acid is stronger?

Answer 1

hey ur answer is:-
4.0x(tex)10^{\tex}
=1.9x[tex]10^
={-5}[tex/]mole
hope it helps you

Answer 2

In a chemical equilibrium there are finite concentrations of reactants and products and these concentrations remain constant with time.

It provides quantitative determination of chemical reaction, It is indicated by the ${ K }_{ c }$.

The equilibrium constants of HCN and HAc (Hydrogen Actinium) are $4.0 \quad \times \quad 10^{ -10 } and 1.9\quad \times \quad 10^{ -5 } mole/L$ respectively.

HAc stronger since it has higher dissociation constant i.e., it would release more ${ H }^{ + }$ ion in solution than HCN.
