Types of Equillibrium

Q.

Review the equilibrium and choose the correct statement

$HCl{O}_4+H_{2}O\rightleftharpoons H_3{O}^{+}+Cl{O}_4^{-}$

1. $HCl{O}_4$ is the conjugate acid of $H_{2}O$

2. $H_3{O}^{+}$ is the conjugate base of $H_{2}O$

3. $Cl{O}_4^{-}$ is the conjugate base of $HCl{O}_4$

4. $H_{2}O$ is the conjugate acid of $H_3{O}^{+}$

Q. Which of the followings is incorrect?

1. According to law of mass action, rate of a chemical reaction is proportional to molar concentration of reactants.
2. If $K_c›1$ then products are present predominantly at equilibrium.
3. Catalysts increase the rate of forward reaction as well as backward reaction.
4. Value of equilibrium constant increases with increase in temperature.
