How can one tell if a reaction has reached equilibrium
the concentrations of products and reactants stop changing.
What is used to describe the conditions of a reaction at equilibrium
Which of these does not describe a significant ethical dilemma in the drug industry
A drug for blood pressure is absorbed in the colon.
How is the Hfusion used to calculate the energy needed to melt a mass of solid
Grams solid mol/g Hfusion
How much energy is consumed by thawing 4.3 g ice
4.3 g * 1 mol/18.02 g * 6.03 kJ/mol
How is the Hfusion used to calculate the mass of solid that 1kJ of energy will melt
1kJ 1/Hfusion g/mol solid
What could make G become negative at a given enthalpy and entropy
How does the H reaction relate to the Hf of molecules involved in a reaction
Hreaction = Hf products - Hf reactants
Which has the smallest rate constant k
chemical changes causing leaves to brown in the fall
Which direction of the reaction is favored at 298 k room temperature use the reaction I2s I2g when H 62.4 kJ.mol-1 and S 0.145 kJ.mol-1.k-1
Gas phase Iodine in open cylinder
According to the rate law how do concentrations affect rate
The rate increases as concentrations increase.
What is the enthalpy of reaction-
The enthalpy of a reaction is the amount of heat absorbed in the
reaction.
