Calculate the equilibrium constant reaction CO(g) + H2(g) H2CO(g), given that for the production of liquid methanal, ∆rG −◦ = +28.95 kJ mol−1 at 298 K and that the vapor pressure of methanal is 1500 torr at the given temperature.
The following are Biophysical Chemistry Questions:
When we are determining the equilibrium affinity (K) for a binding reaction or the rate constant (k) for a reaction, why do we make multiple measurements?
Why is it useful to put one (or more) reagents in great excess of the other (for equilibrium analysis or kinetic analysis?)
Why do you start learning about heat and work in thermodynamics witht the ideal gases instead of chemical reactions?
