Torsional Strain

How does the energy/movement make a molecule go from an eclipsed to staggered conformation?

Zero Order Meaning

If the reaction is a zero order, and the rate of reaction is independent, how come a slope still exists for the straight line?

Problem 8.31

How do we know what to do when pressure or volume is constant?

As in question 8.31, it asks for the heat released at a constant pressure and then a constant volume. What do we do for it, in the ideal gas law when we solve for the heat?

Reversible Systems

In the textbook, it discusses how reversible processes:if the external and internal pressure were to be the same (while temperature is being held constant) is there still work to be calculated?

Re: Calculating Enthalpy with Bond Enthalpies

When calculating the total enthalpy in this case, the easiest way is to draw it because that way you can visualize which bonds remain together and which will be broken, and then possibly reformed (but with another molecule).
