A 1.50 mol sample of an ideal gas at 245 K and a pressure of 0.75 bar is altered by some process that takes it to a state in which its temperature is increased to 295 K and its pressure is increased to 0.90 bar. What will the enthalpy change of the gas in this process be?
Consider the shown reaction, for which the standard reaction enthalpy has a value of at a temperature of 298 K. What is the value of for this reaction at ?
Consider the shown reaction, for which the standard reaction enthalpy is . Calculate the value of for this reaction and determine whether any thermodynamic work is done on or by the reaction system if the reaction is carried out at a constant pressure. Assume that the gases in this reaction exhibit ideal gas behavior at and .
