Consider the following reaction: 3D(aq) + 2E(a) As) + 2B(a) Some A and B are placed in a reaction vessel and the reaction is allowed to proceed. After 30 minutes, the contents of the reaction vessel are sampled. After 30 more minutes, the con have not changed during the last 30 minutes. The concentrations are: tents of the reactor are again sampled. The concentration of reagents in the reactor [B]- 3.2 M [D]- 2.7 M [E] 1.8 M What is Keq for this reaction?

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
