Question
Chapter 12, Problem 70QP
Interpretation Introduction
Interpretation:
The reason that the position of the equilibrium is product-favored at
Concept Introduction:
The equilibrium rate is highly affected by a change in temperature.
In an endothermic reaction, the equilibrium shifts toward the right with an increase in temperature.
In the case of an exothermic reaction, heat is released; so, an increase in temperature shifts the equilibrium toward the left.

A chemist titrates 70.0 mL of a 0.7089 M hydrocyanic acid (HCN) solution with 0.4574M KOH solution at 25 °C. Calculate the pH at equivalence. The pK of
hydrocyanic acid is 9.21.
Round your answer to 2 decimal places.
Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added.
