Which term is the force per unit area or collisions with the walls of the container? volume
volume

number of moles
number of moles

pressure

temperature

yes it is balanced

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
