Question

Based on the Heats of Reaction at 101.3 kPa and 298K chem reftable, which change occurs when pellets of solid NaOH are added towater and stirred? a) water temp decreases & heat energy stored as chemenergy b) water temp increases & heat energy stored as chemenergy c) water temp increases & chem energy converted to heatenergy d) water temp decreases & chem energy converted toheat energy ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I am quite certain that you do not need the referance tablesfor NY state chemistry, but they might help. I have no cluewhat the answer would be and would like an answer and thouroughexplaination. Thanks in advance!

Explanation / Answer

Ans: (c) The chemical energy stored in NaOH (s) is converted to heatenergy. Actually the reaction NaOH (s)  <-------> NaOH (aq) is exothermic and gives outheat.
