In which case temperature increase is highest

    1. The problem statement, all variables and given/known data
    In which case of mixing of a strong acid and a base each of 1 N concentration, temperature increase is highest.

    A)20ml acid-30ml alkali
    B)40ml acid-40ml alkali
    C)25ml acid-25ml alkali
    D)35ml acid-15ml alkali


    2. Relevant equations
    Law of Equivalents

    3. The attempt at a solution
    Using the law of equivalents I have
    [itex]N_{1}V_{1}=N_{2}V_{2}[/itex]
    Since both are 1 N
    [itex]∴V_{1}=V_{2}[/itex]
    So I am now left with options B and C but I don't have any clues how to differentiate between the two. Speaking in layman's term in option B the volume is more so temperature increase will be highest(Fortunately this is correct answer:wink:) but I need a scientific reasoning for this.

    B is not the only correct answer.

    q=mcΔT, solve for ΔT, see if it helps.

    I don't know q,m and c. How can I solve it?
