The Following Questions Often Assume That a Truncated Table of Standard-State

The following questions often assume that a truncated table of standard-state thermodynamic data is attached to the exam.

A) 30^oC
B) between 20^oC and 30^oC
C) between 30^oC and 40^oC
D) 40^oC
E) insufficient information given to decide
