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 ...

T or F: A biochemical reaction, without a catalyst or thermodynamic coupling, takes 50 years to reach a state of equilibrium. W/o more information, we cannot make a determination on either the value of the Keq constant or the positive or negative value of the DeltaG of the reaction Correct Answer-False T or F: Due to its small size, the amino acid glycine can be found in tight turns in a protein structure Correct Answer-True T or F: The Delta G of a reaction is defined as the energy requir...

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...

ammonium carbonate correct answers (NH4)2CO3 Heisenberg Uncertainty Principle correct answers Cannot know both the momentum and position of an object with absolute certainty Bose-Einstein Principle correct answers Collection of atoms cooled close to absolute zero will coalesce into a single quantum state Le Chatelier's Principle correct answers reversible process, the application of stress to the system will cause the system to respond in a way that will relieve this stress Pauli Ex...

Phototrophs - Organisms that capture energy from sunlight Heterotrophs - Organisms that obtain organic carbon compounds by consuming other organisms Autotrophs - organisms that make their own organic carbon from inorganic sources Chemotrophs - Organisms that derive their energy directly from organic molecules such as glucose First law of thermodynamics and relation to energy - Energy is neither created nor destroyedenergy of the starting materials for a reaction will equal the sum of energi...

If the G'° of the reaction A -> B is -40 kJ/mol, under standard conditions the reaction: A) is at equilibrium. B) will never reach equilibrium. C) will not occur spontaneously. D) will proceed at a rapid rate. E) will proceed spontaneously from left to right. - E) will proceed spontaneously from left to right. For the reaction A - B,G'° = -60 kJ/mol. The reaction is started with 10 mmol of A; no B is initially present. After 24 hours, analysis reveals the presence of 2 mmol o...
