True

Explanation:

Suppose you have an equilibrium of the type.

A + B + heat ⇌ C + D

Le Châtelier's Principle states that a system at equilibrium will respond to a stress in a way that will remove the stress.

An endothermic reaction absorbs heat. If the system is at equilibrium and you add a stress by increasing the temperature (adding heat), the system will respond in a way that removes the heat.

The position of equilibrium will move to the right (towards the products).
