Two solutions (the system), each of 25mL volume and at25 o C are mixed in a beak

Question

Two solutions (the system), each of 25mL volume and at25oC are mixed in a beaker. A reaction occursbetween them and the temerature rises to 350C. After the products have equilibrated with the surroundings, thetemperatire is again 25oC and the total volume is50mL. No gases are involved in the reaction. Which oneof the following relationships concerning the change from initialto final states (both at 25oC) is true? a.) E = 0 b.) H = 0 c.) E > 0 d.) w = 0 e.) q = 0 Two solutions (the system), each of 25mL volume and at25oC are mixed in a beaker. A reaction occursbetween them and the temerature rises to 350C.
