The compound IrH3(CO)(P(C6H5)3)2 exists in two forms: the meridional ("mer") and facial ("fac"). At 25°C in a nonaqueous solvent, the reaction mer → fac has a rate constant of 2.33 s-1 , and the reaction fac → mer has a rate constant of 2.10 s-1 . What is the equilibrium constant of the mer-to-fac reaction at 25°C?

Apeak with a retention time of 407 s has a width at half-height (w1/2) of 7.6 s. a neighboring peak is eluted 17 s later with a w1/2 of 9.4 s. a compound that is known not to be retained was eluted in 2.5 s. the peaks are not baseline resolved. how many theoretical plates would be needed to achieve a resolution of 1.5?
