(a)
Interpretation: The mixture at equilibrium needs to be estimated for K equal to 2.0.
Concept Introduction: For any reaction, the reaction quotient can be calculated by taking the ratio of the concentration of the product to the reactant. For a reaction at equilibrium, the reaction quotient is equal to the equilibrium constant.
(b)
Interpretation: The three mixtures need to be ranked from lowest to highest change in Gibbs free energy.
Concept Introduction: For a spontaneous reaction, the sign of change in Gibbs free energy is negative. If the value of Q is less than K, the reaction moves in the right direction to increase the concentration of the product. Also, if the value of Q is greater than K, the reaction moves in the left direction to increase the concentration of reactants.
(c)
Interpretation: The sign of change in Gibbs free energy of reaction needs to be identified if each non-equilibrium mixture approaches equilibrium.
Concept Introduction: Any reaction moving spontaneously will have a negative value for change in Gibbs free energy.

CHEMISTRY:MOLECULAR...(LL)-W/CONNECT
- In the image, the light blue sphere represents a mole of hydrogen atoms, the purple or teal spheres represent a mole of a conjugate base. A light blue sphere by itself is H+. Assuming there is 2.00 L of solution, answer the following: The Ka of the left & right solution is? The pH of the left & right solution is? The acid on the left & right is what kind of acid?arrow_forwardNonearrow_forwardNonearrow_forward
- Nonearrow_forwardWhat spectral features allow you to differentiate the product from the starting material? Use four separate paragraphs for each set of comparisons. You should have one paragraph each devoted to MS, HNMR, CNMR and IR. 2) For MS, the differing masses of molecular ions are a popular starting point. Including a unique fragmentation is important, too. 3) For HNMR, CNMR and IR state the peaks that are different and what makes them different (usually the presence or absence of certain groups). See if you can find two differences (in each set of IR, HNMR and CNMR spectra) due to the presence or absence of a functional group. Include peak locations. Alternatively, you can state a shift of a peak due to a change near a given functional group. Including peak locations for shifted peaks, as well as what these peaks are due to. Ideally, your focus should be on not just identifying the differences but explaining them in terms of functional group changes.arrow_forwardQuestion 6 What is the major product of the following Diels-Alder reaction? ?
