Self-Test 8.11A (6th edition)

Postby 504909207 » Sat Feb 23, 2019 9:07 pm

can someone please explain the process of this question?

Self-Test 8.11A When 0.231 g of phosphorus reacts with chlorine to form phosphorus
trichloride, PCl3, in a constant-pressure calorimeter of heat capacity 216 J·(&C)$1,
the temperature of the calorimeter rises by 11.06 &C. Write the thermochemical equation
for the reaction.

first you should write the rxn, then balance P + Cl -> PCl3, then use the equation: n x (Cp) x (change in temperature)
