Is sublimation of iodine exothermic?

This Youtube shows Iodine subliming at room temperature (an endothermic process absorbing energy), and then they place a cold surface above it, and demonstrate deposition as the vapor converts directly to a solid (an exothermic process).

Is sublimation of co2 exothermic?

It’s endothermic. This is because sublimation requires energy in some form to convert a solid to a gas.

How do you know if it is exo or endo?

When energy is released in an exothermic reaction, the temperature of the reaction mixture increases. When energy is absorbed in an endothermic reaction, the temperature decreases. You can monitor changes in temperature by placing a thermometer in the reaction mixture.

Why is sublimation exothermic?

Sublimation is an endothermic process since it requires some form of energy to convert the solid into a gas component. During sublimation, heat energy is usually supplied in order to bring about the physical change from a solid to gas.

Is sublimation deposition or exothermic?

Endothermic

Is sublimation of ice endothermic or exothermic?

Sublimation is the process in which a substance changes its physical state from solid to gas, without entering liquid state. Thus, sublimation of dry ice requires input of heat energy. Hence, it is an endothermic process.

Is iodine exothermic or endothermic?

The enthalpy change of formation of hydrogen iodide ( from its elements, under standard conditions) is +26.5 kJ/mol. This means on your energy diagram the products (2HI) should be 53kJ/mol higher than the reactants as this reaction is endothermic

Why is the sublimation of iodine endothermic?

It’s endothermic. This is because sublimation requires energy in some form to convert a solid to a gas. Usually, heat energy is supplied to conduct sublimation to bring about the physical change from a solid to a gas.
