The enzyme succinoxidase adds oxygen to succinate to give fumarate. The reaction follows Michaelis-Menton kinetics. The following rate data were determined for a solution in which the enzyme concentration is 10.0 uM: [S](mM) ----------------- 0.33 10.00 vo (uM s-1) at 20 C ----- 0.50 1.17 ...continues

Enzyme kinetics and ligand binding
A protein P is at a concentration of 10-4 M and a substance X that binds to the protein is added at a concentration of 10-5 M. After ten minutes it is found that there is, on the average, 1 X bound per 100 molecules of P. If [P] = 10-3 M and [X] = 10-4 M, after ten minutes there is 1 molecule of X bound per 10 molecules of P. ...continues
Estimate the fugacity of nitrogen gas at 50 bar and 298 K
I have attached the graphs. I don't think the first one is useful, but i needed to plot the data and find the heat of vaporization. Hence, the reason for the second graph. I know that the slope is equal to the heat of vaporization/RT but I don't think I am getting the right answer.
