b) Assume that the equilibrium constant for the above reaction is Kblue and the total pressure at equilibrium is Ptot. Show that the mole fraction of B (xB) present at equilibrium for the reaction above is given by:

indium, and thallium have three electrons i think

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.

the answer is 75.0%.
