Question

A thermometer that was used in a calorimeter was consistently 2.7 C too high.  How would this affect the calculations of ?H for the reactions conducted in the calorimeter?.

Answer

Percent yield would be low

Experimental ?H would be less than the theoretical ?H

No effect

Experimental ?H would be greater than the theoretical ?H

Percent error would be high

Percent yield would be low

Experimental ?H would be less than the theoretical ?H

No effect

Experimental ?H would be greater than the theoretical ?H

Percent error would be high

Explanation / Answer

C- No effect

since dH = mass x specific heat x temp change

here temp change is crucial , since thermometer is constantly 2.77 C high it doesnot effect calculations
