Question
The reaction A B has a strong-AG value, but the reaction docs not proc A) Entropy in the universe will not increase B) Oxygen in required for all reactions C) Reactions need a + AC, to proceed spontaneously D) Too few substrates have sufficient intrinsic energy to overcome the activation energy 14) eed. This may bebe cause E) The reaction needs to be coupled to reaction with an even greater -AG 15) In"plain English, what is (i (i.e., what is R" etc) RTIndsle [SI) formula telling us and what are the individual components What does G--2303RT* log(K'eq), expressed in units Joules/mole, signify? A) Free energy change of water B) Free energy change of a scalar chemical reaction headed toward equilibrium 16) Free energy change of a scalar reduction-oxidation reaction headed toward equilibrium D) F ree energy change of a neutral solute moving across a membrane toward equilibrium E) Free energy change of a charged solute moving across a membrane toward equilibrium 17) G RT *ln([1]c [1]) + ZFE is the electrochemical potential difference of an ion. Based on this equation, name at least three variables that contribute to the distribution of the ion? (3 variables 3 pts) 18) Hydrogen bonding gives water the properties of adhesion, cohesion and surface tension. Describe each. 3 points)Explanation / Answer
14). The answer will be A. Only the reaction which increases the entropy of the universe alongwith have negative G will be favoured.
15). G is the change in Gibbs free energy that indicates whether a reaction is spontaneus or not, R is the ideal gas constant (8.314 J/mol-K), T is the temperature in Kelvin and Sc and So are entropy of closed and open system.
This equattion very simply gives us an indication of how far the standard state for a particular reaction is from achieving the equlibrium condition. A smaller value of G means the standard state is closer to equilibrium. The ultimate driving force in nature is Entropy, which is the degree of disorderness. Since the system plus surrounding is a closed and isolated system therefore only the spontaneous processes allowed are those which increase the entropy.
16). It indicates the free energy change of a scalar chemical reaction headed towards equilibrium.
