A) is x > y
B) does not exist
C) is x = y
D) is x < y
Correct Answer: A
Solution :
[a] \[B{{r}_{2}}\left( I \right)\to 2Br\left( g \right);\] \[\Delta H=x\] \[kJ/mol\] \[B{{r}_{2}}\left( g \right)\to 2Br\left( g \right);\] \[\Delta H=y\]\[kJ/mol\] \[B{{r}_{2}}\left( I \right)\to B{{r}_{2}}\left( g \right)\to 2Br\left( g \right)\] \[\therefore \,\,\,\left[ x>y \right]\]
