can someone help me with this question

You have identified found an enzyme in the lab freezer labeled “bloggsose kinase/ GTP” which catalyzes the reaction: 

  bloggsose + GTP ⇔ bloggsose-phosphate + GDP 

You want to determine whether it is still active, so you place in solution in an eppendorf tube a very tiny amount of pure bloggsose kinase and a mixture of bloggsose and GTP and allow the reaction to proceed to equilibrium. Then you carefully assay the concentrations of each reactant and product, and find that they are:

[bloggsose] = 12 mM[bloggsose-phosphate] = 0.35 M[GTP] = 12 mM[GDP] = 0.35 M

(a) Calculate the Keq for this reaction.

(b) Using the Keq, calculate ∆Go for this reaction.
