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 :
As the reaction is carried out in a closed versel (bomb calorie meter), no expansion or contraction can take place, \[\therefore Work done, w=0\] Hence by 1st law of thermodynamics, \[\Delta U=q\] But q is -ve, i.e. < 0 As the reaction is exothermic \[\therefore \Delta U<0\]You need to login to perform this action.
