Q-6C867 (Set 2) – Part a(iii)

The enthalpy change of the neutralization, \( \Delta H \) in \( kJ~mol^{-1} \), may be found from the temperature rise, \( \Delta T \) and the volume, V, of HCl in mixtures where HCl is the limiting reagent, using the expression:
\( \Delta H=\frac{50.0\times 4.18\times \Delta T}{2.00\times V} \)
Determine the percentage uncertainty in the temperature rise, using the precision with which the temperature was measured.
