Consider a chemical reaction which has achieved a state of equilibrium. Which of the following statements are true in this equilibrium state? (Mark all that apply.) A. The concentrations of reactants and prodcuts are still changing with time. B. The concentrations of reactants and products is no longer changing with time. C. The rate of the forward reaction is greater than that of the reverse reaction. D. The rate of the reverse reaction is greater than that of the forward reaction. E. The rates of the forward and reverse reactions are equal.

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
