#1
Front (Question)
Exothermic
Back (Answer)
• Heat energy is given out • If the energy to break bonds is less than the energy to form bonds • (-ΔH)
#2
Front (Question)
Endothermic
Back (Answer)
• Heat energy is taken in • If the energy to break bonds is more than the energy to form bonds • (+ΔH)
#3
Front (Question)
Heat energy change
Back (Answer)
Heat energy(J) = mass(Kg) x specific heat capacity(J/kg°C) x change in temperature(ºC) Q = mcΔT
#4
Front (Question)
Change in enthalpy
Back (Answer)
Change in enthalpy(J/mol) = - heat energy(J) / moles(mol) ΔH = -Q/n
#5
Front (Question)
Enthalpy
Back (Answer)
Bond energy
