n three trials of a reaction to determine the concentration of a sodium hydroxide solution, the average volume of 0.1255 mol/L sulfuric acid was 19.97 mL to neutralize 20.00 mL of the base. What was the concentration of the sodium hydroxide solution? Determine the original pH value of the base.

How does the value of the equilibrium constant show that a reaction reaches equilibrium very quickly? (a) the equilibrium constant is large. (b) the equilibrium constant is small. (c) the equilibrium constant is zero. (d) the value of the equilibrium constant does not show how quickly a reaction comes to equilibrium.
