28. The reaction 2SO3 (g) <> 2SO2 (g) + O2 (g) is endothermic. If the temperature is increased, a) More SO3 wil be produced b) Kc will decrease c) No change will occur d) Kc will increase e) The pressure will decrease

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 0.42 is that is an option. this question provides no info

you need to stop taking that class
