Question

Consider the following reaction: CO(g) + 2 H_2(g) rightarrow Ch_3OH(g) Delta H = -90.7 kJ. Describe the flow of heat in this reaction. It is a) absorbed because this is an endothermic reaction b) released because this is an endothermic reaction c) absorbed because this is an exothermic reaction d) released because this is an exothermic reaction e) no heat is released or absorbed as this is an isothermal process calculate the amount of heat transferred when 107.3 g of CH_3OH is synthesized by the above reaction at constant pressure.

Explanation / Answer

47. The flow of energy in this reaction is exothermic as the heat is released from the reaction thus the enthalpy is negative. Thus as enthalpy is negative delta H = -90.7kJ , this means energy is released and the reaction is exothermic

According to this explanation , the correct option is (d)
