explain how 3A was solved and what it means
In Class Exercise 3. Creatinine Kinase catalyzes the following reaction: ATP + Creatine ADP + Phosphocreatine If the [ATP]=4mM,ADP=0.15mM, [phosphocreatine ]=2.5mM, and [creatine]=1 mM, what is the G for the forward reaction? G=G+RTLnQ G=12.6kJ/mol+(8.3145J/K/mol)(298K)Ln[(2.5mM0.15mM)/(1mM4mM)=2.367 =12.6kJ/mol5.9kJ/mol=6.7kJ/mol b. Is it spontaneous or non-spontaneous? G>0 so the forward reaction is not spontaneous. c. Can you tell how fast the reaction will go from the information I've provided? No. Not for the reverse reaction either. Remember that G values do not tell you anything about reaction rates
