If a weak acid has a dissociation constant of 2.2×10^−8, what is the dissociation constant of its conjugate base?
A weak acid has a dissociation constant Ka = 2.5x10-2. Calculate the percentage dissociation for a 0.0750 m solution of this acid assuming a) ideal conditions and b) non-ideal conditions
How does the molarity change if the volume is constant but more solute is added? Molarity (M) = moles solute liter solution 1. Select cobalt(II) nitrate from the pull-down menu, and select "show values". Adjust the solute and solvent amounts and record the results in the table below. Hitting the reset button will return the solute and solution volume sliders to 0.500 moles and 0.500 L, respectively. Complete the table. Cobalt(11) nitrate Solute Amount Solution Volume Molarity 0.500 mol 0.500...
Describe why Michaelis constant (km) and the dissociation constant (Kd) should not be considered to be the same. Use the rate constant definitions of these terms in your explanation, and also indicate in what case Km & Kd can be considered to be the same?

Calculate the association constant and dissociation constant for the binding interaction of a small molecule inhibitor of a protein. When the two are mixed in amounts containing the same amount of moles or equimolar amounts the system is permitted to reach equilibrium. The concentration are Protein with 120 μM, Inhibitor with 120 μm. and Protein-Inhibitor Complex with 1.5 mM
The Km can be considered to be the same as the dissociation constant K for E+ S binding it: the concentration of [ES] is unchanged k1 >> K2 ES --> E+ P is fast compared to ES -->E+S k2<<k-1 this statement cannot be completed because Km can never approximate Ks 2. Muscle contraction is triggered: by conformational change in myosin and actin in response to an increase in the cytoplasmic Ca2+ concentration in response to an increase in the cytoplasmic...
