Heat transfer between two substances is affected by specific heat and the?

The correct answer is "amount of time and area of physical contact between the substances".

Explanation:

Heat transfer between two substances is affected by the specific heat and the amount of time and area of physical contact between the substances. The contact time is critical for the heat transfer to be complete. If the time is reduced, the heat is not transferred completely. The area of physical contact increases the amount of heat transferred as it increases.

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.
