Multiple Choice

The production of gaseous reaction products will generate pressure in a closed vessel.

Explanation:
In a closed, fixed-volume system, adding gas increases pressure. When a reaction produces gaseous products, the number of gas molecules inside the container goes up. Since the volume doesn’t change, those extra molecules collide with the container walls more frequently, raising the pressure (P rises with n at constant V and T). If the reaction also releases heat, the temperature can climb and push pressure even higher. If no gas is produced, there’s no pressure increase due to gas generation. So the statement is true.
