The reason for rapid increase in boiling point from methane to ethane to propane in comparison to heptane to nonane and from nonane to decane should be explained. Concept Introduction: The compound containing longest parent chain of carbon have high boiling point due to the bulkiness of the structure while the compound containing shortest parent chain of carbon have low boiling point. Moreover, straight chain have large surface area which increases the possibility of area of contact with other chain which results in higher Vander Waal forces between them and thus increases the boiling point.

Given a system with an anodic overpotential, the variation of η as a function of current density- at low fields is linear.- at higher fields, it follows Tafel's law.Calculate the range of current densities for which the overpotential has the same value when calculated for both cases (the maximum relative difference will be 5%, compared to the behavior for higher fields).

Using reaction free energy to predict equilibrium composition Consider the following equilibrium: N2 (g) + 3H2 (g) = 2NH3 (g) AGº = -34. KJ Now suppose a reaction vessel is filled with 8.06 atm of nitrogen (N2) and 2.58 atm of ammonia (NH3) at 106. °C. Answer the following questions about this system: rise Under these conditions, will the pressure of N2 tend to rise or fall? ☐ x10 fall Is it possible to reverse this tendency by adding H₂? In other words, if you said the pressure of N2 will tend to rise, can that be changed to a tendency to fall by adding H2? Similarly, if you said the pressure of N will tend to fall, can that be changed to a tendency to rise by adding H₂? If you said the tendency can be reversed in the second question, calculate the minimum pressure of H₂ needed to reverse it. Round your answer to 2 significant digits. yes no ☐ atm Х ด ? olo 18 Ar
