What is the third law of thermodynamics? Correct Answer The entropy of a perfect crystal is zero. What is the second law of thermodynamics? Correct Answer As a whole, the universe always tends towards increasing entropy. What is the relationship between number of microstates and entropy? Correct Answer More microstates = higher entropy What is the relationship between temperature and entropy? Correct Answer Temperature increases, entropy increases (direct) What is the relationship be...

Exam 1 Correct Answer- A reaction consists of a reactant "R" being converted into a product "P". The change in enthalpy of the conversion is 5 kJ/mol, while the change in entropy is 35 kJ/mol. Therefore, thermodynamic coupling is not required for this reaction to reach an equilibrium. True/False Correct Answer-True Which of the following is true regarding a reaction that has a ΔG° = 0. The concentrations of the reactants and products are equal. The reaction will eventually arriv...

Biology 1201 LSU Exam 2 Questions and Answers 100% Pass What type of chemical reaction is without outside energy? Spontaneous (exergonic/downhill) NOT INSTANTANEOUS -decreasing enthalpy and increasing entropy What is the equation for Free Energy? deltaG=deltaH-TdeltaS -free enrgy=enthalpy-(temp.)(entropy;disorder) -high deltaS=low delta G Entropy Disorder: -breakdown: increase in disorder, more parts -synthesis: decrease in disorder, less parts -high entropy=low free energy ...

CEM 142 First Exam Latest Update Already Passed Define and give examples of open, closed and isolated systems Open system-both matter and energy can enter or leave (beaker without a lid, pour your hot drink into a mug) Closed system- the amount of matter is constant and only energy can enter or leave (cup of coffee with a lid on it) Isolated systems- neither energy nor matter would move between the system and the surroundings (Styrofoam coffee cup with a lid on) Explain the dif...
