Calculate the molar heat of reaction for the NaOH(aq) using the data obtained from this experiment. (this is a neutralization question)
Initial temp. = 29.9
C = 1.0 mol/L
Initial temp. = 29
Final temp of the two contents = 32.9
This is my solution:
El = Eg
nH = mc∆t
0.05mol x H = 0.08L x 4.19 x 3.9
H = 26.15
The standard molar heat of neutralization of sodium hydroxide,
is -57 kJ/mol.
so shouldn't my calculated value be close to the standard value? Please tell me whether my solution is right or wrong!
Thank you in advance =)
