Unformatted text preview: sample testZ When the reaction A —> B + C is studied, a plot MIA} vs. time gives a straight line with a positive slope.
What is the order ofthe reaction? A. zero 3. ﬁrst
C. second 3. third .3. More intonnation is needed to determine the order. The decomposition of dinitrogen pentaoxide has an activation energy of 102 karnoi and Mum = + 55
kJr'rno]. What is the activation energy for the reverse reaction? A. 2? kamol
B . 4? klfrnol
C. 55 kamol
D. [00. kJEmoI E. More information is needed, since this is a Hess' Law calculation. C onsider the reaction
