Why or why not?This is a plot under standard conditions of free energy corresponding to a chemical reaction of A+B to C+D. What will happen if only C+D are present under standard temperature and pressure? Please explain why.Consider the following process: NaCl(s) water−→−−water→ Na+(aq) + Cl-(aq); ΔH = +4.2 kJ/mol Under what conditions (temperature) would you expect this process to be spontaneous? Select a relatively high temperature and a relatively low temperature, calculate (estimate) the relative values of ΔG to support your conclusion.

- Calculate the Gibbs free energy change (G) for the following chemical reaction: glutamate + NH3 glutamine + H2OThe reaction occurs at 293 K, the change in heat (H) = 4103 cal, and the change in entropy (S) = 2.4 cal/K.Regarding the reasoning for the Michaelis-Menten equation to be unsuitable for accurate analysis of experimental data, select all that apply: It is nonlinear It is only valid for reactions at equilibrium It is not valid under experimental conditions Extrapolation to Vm is inaccurate and therefore Km also cannot be accurately describedThe total concentration of enzyme in a reaction, [E], is made up of the concentration of enzyme bound to substrate, [ES], and the concentration of enzyme still free in solution, [Ef]. Similarly, the total amount of substrate is made up of [Sf] and [ES]. We can assume that the concentration of enzyme is much less than that of the substrate, [E] << [S]. Assuming the steady state condition and the relationships between [E], [Ef] and [ES], and similar ones for S, given in lectures, derive an expression for the saturation factor, , in terms of [S] and . (Note that [E] and [S] denote the total amounts of enzyme and substrate added to the reaction, respectively. You may assume that [S]>>[E].)
