Question

A) The relationship between delta G°' and delta G is best described as:

B) For the two reactions (a) AB delta G°’ = 2 kJ mol–1, and (b) X Y delta G°’ = –3.5 kJ mol–1 , which of the following statements is correct?

C) If Keq = 1, what is the delta G°’?

D) If Keq > 1, what is the delta G°’?

E) What is the common strategy by which catalysis occurs?

F)

The relationship between delta G, and delta G is best described as: Determined by the temperature Described by changes in K Differing from standard state to physiological or actual concentrations of reactants and products. Dependent on the reaction mechanism of the reaction. Differing only in terms of the types of reactions used for each value

Explanation / Answer

A) Determined by the temperature. Because delta G = delta G ° + RTlnK

B)for a spontaneous reaction delta G should be negative and hence option b is correct for which delta G is -3.5 and hence reaction takes place quickly.

C) delta G° = -RTln k

Ln 1= 0 and hence delta G° =0

D) when Keq>1 then ln k will be more positive and hence G° will be more negative.

E) Catalyst increases the rate if reaction by decreasing the activation energy so it stabilises the transition state and hence increases the rate if reaction.

F) As enzyme catalyses both the forward and the backward reaction and hence doesn't favour the reaction in one particular reaction. Hence none of the above.
