If a reaction mixture contains only n 2o and no2 at partial pressures of 1.0 atm each the reaction will be spontaneous until some no forms in the mixture. what maximum partial pressure of no builds up before the reaction ceases to be spontaneous

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 need to have a picture of the atom that way we can answer it

answer carbon and three oxygen atoms;
