A) \[\Delta U<0,\]\[w=0\]
B) \[\Delta U<0,\]\[w<0\]
C) \[\Delta U>0,\]\[w=0\]
D) \[\Delta U>0,\]\[w>0\]
Correct Answer: A
Solution :
[a] \[Zn+{{H}_{2}}S{{O}_{4}}=ZnS{{O}_{4}}+{{H}_{2}}\] In bomb calorimeter, there is no expansion in volume, so, work done will be zero. This reaction is exothermic. So, some heat will be evolved which will result in lowering of internal energy. Hence, \[\Delta U<0\] and \[w=0\]You need to login to perform this action.
