Consider the balanced chemical equation. H2O2(aq) + 3 I^-(aq) + 2 H+(aq) S I3^-(aq) + 2 H2O(l) In the first 10.0 seconds of the reaction, the concentration of I^- drops from 1.000 M to 0.868 M. (a) Calculate the average rate of this reaction in this time interval.

(b) Predict the rate of change in the concentration of H (that is, ∆[H ]>∆t) during this time interval.

Based on the data provided,  the rate of the given reactions are:

a. reaction rate =  0.0132 M/sec

b. rate of change of [H⁺] = 8.8 * 10⁻³ M/sec

What is the reaction rate?

Reaction rate = change in concentration of reactant or product/ time taken

Change in concentration of I⁻ = 1.000 M - 0.868 M= 0.132

time taken = 10 s

reaction rate = 0.132/10

Rate of reaction = 0.0132 M/sec

Rate of change of [H⁺]

From the equation of the reaction 3 moles of I⁻ are used up for every 2 moles of H⁺

Hence, the rate of change of [H⁺] = 0.0132 M/sec * 2/3

rate of change of [H⁺] = 8.8 * 10⁻³ M/sec

Therefore, the rate of the given reactions are:

a. reaction rate =  0.0132 M/sec

b. rate of change of [H⁺] = 8.8 * 10⁻³ M/sec

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
