A student wants to determine the ionization constant of a weak acid. They use the initial concentration and the pH of the solution at a given temperature to calculate the ionization constant. Given that the temperature of the solution is changed by 10°C, how will this affect the ionization constant of the weak acid? Calculate the new ionization constant at the new temperature assuming that no additional acid or base is added to the solution.
