First experiment:
Mass of H3C6H5O7(aq)=36.40g
Mass of NaHCO3(s)=8.00g
Total mass of reaction mixture=44.40g
Initial Temperature= 19.9*C
Final temperature= 3.2*C

A student conducts a second experiment using 36.40g of H3C6H5O7 at an initial temperature of 19.9*C. However, the student adds only 4.00g of NaHCO3. Would the temperature change in the second experiment be greater than, less than, or equal to the temperature change in the first experiment? Justify your answer.
