State specific heat of water increases at a constant rate

Reference no: EM13186727

When determining the enthalpy change for a neutralization reaction involving NaOH and HCl in a coffee-cup calorimeter, which assumption is NOT reasonable?

Q:
The specific heat of water increases at a constant rate.

The specific heats of NaOH, HCl, and the product of the reaction are the same as that of water.

The reaction of NaOH with HCl is stoichiometric and no side reactions occur

Even though some heat may be gained or lost from the coffee-cup and the environment, it is possible to obtain the final temperature by extrapolation from a graph of time versus temperature.
