What defines an exothermic reaction
A reaction that produces heat
How is heat included in the equation of an exothermic reaction
Heat is written as a product of the reaction (apecs answer)
How is the Hfusion used to calculate volume of liquid frozen that produces 1 kJ of energy
1kJ 1/Hfusion g/mol ml/g liquid
Which of the following describes the entropy change of a gas reaction
If there is an increase in the number of gas molecules, then S > 0.
What most determines the entropy of a solid
The crystalline structure of the solid most determine the
entropy of a solid.
How does entropy change in gas reactions
Reactions that increase the moles of gas will increase in
entropy.
Use the reaction I2s I2 g H 62.4 kJ mol S 0.145 kJ molK for Question 10. Which direction of the reaction is favored at 298 K room temperature
It is spontaneous at 2000 K.
What conditions make G always negative
G is always negative when H is negative and S is positive.
What is the value for G at 300 K if H 27 kJmol and S 0.09 kJmolK
What does S0 mean
the system has become more random
What describes the difference between the mechanics of airplane flight and rocket flight
The difference is that you are a mamaguevo y yo se lo meto a tu
hermana.
What is the pH of a solution with H 2.310-6
What chemical reaction describes where energy is absorbed
You think probable to an endothermic chemical reaction.
How is the H fusion used to calculate the energy released when a mass of liquid freezes
grams liquid x mol/g x H fusion
Would form a spontaneous reaction at 298k
What does the second law of thermodynamics say apex
The entropy of the universe is increasing
