Interpretation Introduction

(b)

Interpretation:

The relation of Δ_rG⁰ for the reaction C(s) + CO2(g) → 2 CO(g) to the three reactions shown in the figure should be determined. Δ_rG⁰ for the above reaction should be plotted as a function of temperature. The equilibrium partial pressure of CO(g) at 1000⁰C should be determined if the partial pressure of CO₂(g) is 0.25 atm

It is not unexpected that the methoxyl substituent on a cyclohexane ring prefers to adopt the equatorial conformation.

This effect that provides stabilization of the axial OCH 3 group in this molecule is called the anomeric effect.
