For the following reactions, predict whether the mole fraction of the reactants or products increases or remains the samewhen the volume of the reaction vessel is increased. a. 3: 20; ) + hzrg) = 2hbr(g)b. 20-14(3) ‘——‘ c2h2(g) + 31-12(3)c. 21-11(g) ‘——‘ 12(5) -i- h2(g)

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.

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
