Three student chemists measured 50.0 ml of 1.00 M NaOH in separate Styrofoam coffee cup calorimeters. Brett added 50 ml of 1.10 M HCl to his solution of NaOH. Dale added 45.5 ml. of 1.10 M HCl (equal moles) to his NaOH solution. Lyndsay added 50 ml of 1.0 M HCl to her NaOH solution. Each student recorded the temperature change and calculated the enthalpy of neutralization. Identify the student who observes a temperature change that will be different from that observed by the other two chemists. Explain why and how (higher or lower) the temperature will be different.
