How does the spontaneity of the process relate to the Ksp?

At what points in the Chapman cycle do photochemical reactions take place?

One of the important reactions in the biochemical pathway glycolysis is the reaction of glucose-6-phosphate (G6P) to form fructose-6-phosphate (F6P): G6PF6PG298=1.7kJ (a) Is the reaction spontaneous or nonspontaneous under standard thermodynamic conditions?. (b) Standard thermodynamic conditions imply the concentrations of G6P and F6P to be 1 M, however, in a typical cell, they are not even Close to these values. Calculate G when the concentrations of G6P and F6P are 120 M and 28 M respectively, and discuss the spontaneity of the forward reaction under these conditions. Assume the temperature is 37 C.

When glucose, C6H12O11, is metabolized to CO2 and H2O in living systems, the first step is the conversion of glucose to glucose-6-phosphate. glucose+H3PO4glucose-6-phosphate+H2OG=13.4kJ This nonspontaneous reaction can be made to proceed by coupling it with the hydrolysis of ATP. ATP+H2OADP+H3PO4G=31.0kJ (a) Write an equation for the coupled reaction and calculate G°. (b) Estimate the number of moles of ATP required to convert glucose to glucose-6-phosphate.

What is the difference between G, G, and G 298 for a chemical Change?

Is the formation of ozone (O3(g)) from oxygen (O2(g)) spontaneous at room temperature under standard state conditions?

Consider planet Earth as a thermodynamic system. Is Earth thermodynamically or kinetically stable? Discuss your choice, providing as many arguments as you can tosupport it.

Consider the following reactions at 25°C: C6H12O6(aq)+6O2(g)6CO2(g)+6H2O G=2870kJ ADP(aq)+HPO42(aq)+2H+(aq)ATP(aq)+H2OG=31kJ Write an equation for a coupled reaction between glucose, C6H12O6, and ADP in which G=390kJ .
