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
