Question 1

Use the standard reaction enthalpies given below to determine DrH° for the following reaction:

P4(g) + 10Cl2(g) → 4PCl5(s)DrH° = ?
Given:
PCl5(s) → PCl3(g) + Cl2(g)DrH°= +157 kJ
P4(g) + 6Cl2(g) → 4PCl3(g)DrH° = -1207 kJ

◦ -1786 kJ mol-1
◦ -1835 kJ mol-1
◦ -1050 kJ mol-1
◦ -2100 kJ mol-1
◦ -1364 kJ mol-1

Question 2

Use the standard reaction enthalpies given below to determine DrH° for the following reaction:

2NO(g) + O2(g) → 2NO2(g)DrH° = ?
Given:
N2(g) + O2(g) → 2NO(g)DrH° = +183 kJ
​
1/2 N2(g) + O2(g) → NO2(g)DrH° = +33 kJ

◦ +115 kJ mol-1
◦ -150. kJ mol-1
◦ +238 kJ mol-1
◦ -117 kJ mol-1
◦ -333 kJ mol-1

Drug abusers experience the following scenario: The pleasure given by their drug (or drugs) of choice is so strong that it is difficult to eradicate even after years of staying away from the substances involved. Certain triggers may cause a drug abuser to relapse. Research shows that long-term drug abuse results in significant changes in brain function that persist long after an individual stops using drugs. It is most important to realize that the same is true of not just illegal substances but alcohol and tobacco as well.
