Question

A volume of 4.0 L of gases A(g) and B(g) react to form solid C(s). During the reaction, the system looses 1150J of heat to the surroundings. The volume of the system is negligibly small at the end of the reaction as the gases disappear under atmospheric pressure. What is the change in internal energy of the system?

(A) 1150J
(B) 744.7J
(C) 1555.3J
(D) 1150J
