For a certain gas-phase reaction, the fraction of products in an equilibrium mix

Question

For a certain gas-phase reaction, the fraction of products in an equilibrium mixture isincreasedeither bydecreasingthe temperature or byincreasingthe volume of the reaction vessel. Based on these observations pick thecorrectstatement from the choices below.

For a certain gas-phase reaction, the fraction of products in an equilibrium mixture isincreasedeither bydecreasingthe temperature or byincreasingthe volume of the reaction vessel. Based on these observations pick thecorrectstatement from the choices below. a) Delta H 0 and products are made of smaller molecules than reactants. c) Delta H > 0 and the reaction equation shows more moles of product gases than reactant gases. d) Delta H > 0 and products are made of larger molecules than reactants. e) Delta H

Explanation / Answer

If the fraction of products increases when u raise the temperature, its because its an endothermic reaction. If u increase the volume, u reduce the pressure and the reaction will move to the side where more moles of gas are in, in order to increase the pressure. I think u should read Le Chatelier principle
