Enthalpy of Reaction

ΔH value in an endothermic reaction is a positive number.

• True
• False

What type of reaction is shown in the graph?

• endothermic reaction

• exothermic reaction

H₂ + ½ O₂ --> H₂O + 285 kJ

is an example of a(n)

• Electrical equation

• Heat equation

• Thermochemical equation

C+ O₂ --> CO₂ + 60kJ

what is the ΔH for the reaction?

• +60

• -60

• there is no way to know

How do you calculate Enthalpy of a reaction?

• ΔH = ΔH_products - ΔH_reactants

• ΔT = q / mC

• ΔG = ΔH -TΔS

• E = mc²

Endothermic reactions feel

• warm
• cold

Which symbol represents Enthalpy change?

• ΔH

• ΔT

• ΔG

• ΔS

usually in chemistry the pan here is...

• the system

• the universe

• the surroundings

• system + surroundings
