(a) Revisit Example 1-1. Rework this example using Equation 3-1 on page 75.

(b) What does a negative number for the rate of formation of species (e.g., Species A) signify? What does a positive number signify? Explain.

(c) Revisit Example 1-2. Calculate the volume of a CSTR for the conditions used to figure the plug-flow reactor volume in Example 1-2. Which volume is larger, the PFR or the CSTR? Explain why. Suggest two ways to work this problem incorrectly.

(d) Revisit Example 1-2. Calculate the time to reduce the number of moles of A to 1% of its initial value in a constant-volume batch reactor for the same reaction and data in Example 1-2. Suggest two ways to work this problem incorrectly.
