One version of the First Law of Thermodynamics is expressed as Delta E = q +…

One version of the First Law of Thermodynamics is expressed as Delta E = q + W Which gives the sign convention for this relationship that is usually used in chemistry? C_2 H_5 OH_(l) + 3 O_2(g) rightarrow 2CO_2(g) + 3H_2 O_(g) At 298 K, the change in enthalpy, Delta H, for the reaction above is approximately equal to (A) Delta E + RT (B) Delta E – 2 RT (C) Delta E + 2 RT (D) 5RT – Delta E (E) 2RT – Delta E
