Increasing Temperature will shift the reaction in a direction which absorbs heat as per Le chatelier Principle
here increasing temperature shift equilibrium towards the reactant which is backward process.
So, backward process absorbs heat.
That is backward process is endothermic
Forward reaction must be exothermic
Answer: The reaction is exothermic

Question 28 (5 points) For a particular reaction, increasing the temperature of the reaction at constant pressure and volume increased the formation of the product. Which of the following is true for the reaction? The reaction is exothermic. Increasing the temperature always increases the product formation, so you can't tell if it is endothermic or exothermic. The reaction is endothermic. Temperature changes do not affect the equilibrium.

A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1 atm. The cylinder is also submerged in a large insulated water bath. (See sketch at right.) 1 atm pressure piston .cylinder From previous experiments, this chemical reaction is known to absorb 328. kJ of energy water bath gases The...
