Given Keq = 54.3
Since Keq is greater than 1, there are more product in reaction than reactants
Answer: a
34)

Consider the acid/base equilibrium of bromocresol purple shown in the image above. Why is the basic form of bromocresol purple violet, whereas the acidic form is yellow? Question 6 options: A) The basic form has more p-orbitals overlapping to form pi molecular orbitals and thus has larger conjugation than the acidic form. The more p-orbitals that participate in a conjugated system, the higher the energy of light absorbed. Hence the basic form absorbs shorter wavelengths of electromagnetic radiation than the...
