"Which combination of solutions of HCl and NaOH would produce the largest ΔT?"
a. 50 mL of 1 M HCl with 50 mL of 1 M NaOH
b. 50 mL of 2 M HCl with 50 mL of 2 M NaOH
c. 100 mL of 1 M HCl with 50 mL of 2 M NaOH
d. 100 mL of 1 M HCl with 10 mL of 1 M NaOH
So I know that this is an enthalpy of neutralization problem. Because it is given in kJ/mol, I know that the higher T will be the one with the more moles involved.
a. 50 mmol and 50 mmol
b. 100 mmol and 100 mmol
c. 100 mmol and 100 mmol
d. 100 mmol and 100 mmol.
So now a. is out.
It seems logical to me that the one that is made of higher concentrations will produce a larger ΔT, but if you were to ask me that I would say "just because."
What is the relevant equation that I am missing which includes concentration, and not just number of moles, that I can use to mathematically prove to myself that the one made of stronger concentrations (b) is the one that will provide the largest ΔT?
Thanks so much in advance!
