What is thermal energy
The total kinetic energy of the particles in a system
12 l of ammonia were produced by the haber process how many liters of hydrogen were used during the reaction the reaction took place at stp 0c and 1.0 ATM n2g plus 3h2g 2nh3g
What would cause entropy to increase in a reaction
The products becoming more spread out.
What is true of the enthalpy value of an intermediate reaction
It is multiplied by 2 if the intermediate reaction is multiplied
by 2
What happens when a glass of water is set in the sun until the water evaporates
What does a negative H tell about a reaction
The reaction is exothermic.
What would cause entropy to decrease in a reaction
The products becoming more ordered than the reactants
What information does the latent heat of vaporization give
The energy needed to completely vaporize a mole of a liquid
How is stoichiometry used to calculate energy released when a mass of liquid freezes
Grams liquid × mol/g × Hfusion

What statement describes the potential energy diagram of an exothermic reaction
The potential energy of the reactants is greater than the
potential energy of the products.
