... excellent solvents for the reagent and the reaction products; they do not accelerate the rate of reaction. Polar solvents such as pyridine, dimethylformamide (DMF), dimethylsulfoxide (DMSO), tetrahydrofuran (THF), and acetonitrile are more often used because they can facilitate the reaction. Pyridin ...

TOPIC 11 Further equilibrium 11.1 Chemical equilibrium
... If the amount of H2(g) at equilibrium has increased, then the position of equilibrium has shifted to the left. Since this shift has been caused by an increase in temperature, the reverse reaction must be endothermic. Hence the forward reaction must be exothermic. ...
