Explanation:
Let us recall that;
[H^+] [OH^-] = 1 * 10^-14
Where;
[OH^-] = 1 x 10^-11
Then;
[H^+] = 1 * 10^-14/1 x 10^-11
[H^+] = 1 * 10^-3
pH = -log [H^+]
pH = -log(1 * 10^-3)
pH = 3
Also;
pH + pOH = 14
pOH = 14 - pH
pOH = 14 -3
pOH = 11
A reaction that gives off heat energy is called Exothermic. (Answer).
A reaction that absorbs heat from the surroundings is called endothermic.
The pH changes to a value closer to 7, which is considered neutral.
This, however, only applies to all reactions between strong acids and strong bases. If the reaction either involves a weak acid and/or a weak base, the computation of the final pH may slightly be more complicated.
I think the correct answer among the choices presented above is the third option. An activated complex formed during a chemical reaction is only formed in the forward direction. It is a temporary unstable compound formed when the activation energy of a reaction is attained.
