The report can be formatted as an Instagram post, a series of tweets, or a short TikTok video.

- Instructions:

• Split the class into groups of up to 5 students.

• Each group selects a chemical reaction at equilibrium to explore.

• Use social media to uncover pertinent information about the chosen reaction, including industrial production, biological processes, etc.

• Craft a 'digital report' that includes: a description of the reaction, the involved partial pressures, calculations of the equilibrium constants (Kp and Kc), and their relationship.

• The report should be presented through an Instagram post, tweet thread, or TikTok video, incorporating all gathered information.

• Share the report on the selected social media platform and provide the link to the class and the teacher.

Activity 2 - 🎮 Gamification: The Balance Game
