If you boil water are you increasing delta H (heat), delta E (energy), or delta S (entropy)?
Liquid methanol has a heat capacity of 81.6 J/(K mol). How much heat is required to raise the temperature of 20.0 g of liquid methanol from 25 C to 40.0 C?
Considering the Reaction: 2H2O(l) => 2H2(g) + O2 (g) This reaction has dispersal of matter since a liquid produces two gases, yet the reaction is not spontaneous. Why is this so?
Understanding how the equilibrium constant (Keq) relates to enthalpy change. Introductory thermodynamics. Attachment in Word.
Which reaction is more exothermic? A reaction with Keq=500 or a reaction with Keq=0.002?
Understanding Gibbs Free Energy change. Identifying reactions that are thermodynamically spontaneous.
The attached problem file shows the standard Gibbs Free Energy Change for two reactions. Considering these values, which reaction is more favoured or spontaneous? A reaction with a delta Go = 16 kcal mole-1? Or a reaction with a delta Go = -16 kcal mole-1?
Determining the initial mole and mass fractions of oxygen and nitrogen in a mixture using Dalton's law of partial pressure. Solution in MS Word.
A reaction vessel contained 5 liters of a mixture of N2 and O2 gases at 25oC and 2 atm pressure. The oxygen in the mixture was completely removed by causing it to oxidize with an excess of electrically heated zinc wire contained in the vessel to non-volatile solid ZnO. The pressure of N2 that remained (measured again at 25oC) wa
