A process for the production of 1,3-butadiene results from the catalytic dehydrogenation at atmospheric pressure of 1-butene according to the reaction: C4H8(g) → C4H6(g) + H2(g), heat of reaction is 109780 J/mol. To suppress side reactions, the 1-butene feed stream is diluted with steam in the ratio of 10 moles of steam per mole of 1-butene. The reaction is carried out isothermally at 525°C, and at this temperature 33% of the 1-butene is converted to 1,3-butadiene. How much heat is transferred to or from the reactor per mole of entering 1-butene?

Question
A process for the production of 1,3-butadiene results from the catalytic dehydrogenation at
atmospheric pressure of 1-butene according to the reaction: C4H8(g) → C4H6(g) + H2(g), heat of
reaction is 109780 J/mol. To suppress side reactions, the 1-butene feed stream is diluted with
steam in the ratio of 10 moles of steam per mole of 1-butene. The reaction is carried out
isothermally at 525°C, and at this temperature 33% of the 1-butene is converted to 1,3-butadiene.
How much heat is transferred to or from the reactor per mole of entering 1-butene?
