This research aimed to achieve the following objectives: 1) to determine the efficiency of the CAI titled “Chemical Reaction and Equation” based on the 70/70 criterion 2) to compare academic achievement and learning progress between the control and experimental groups and 3) to study satisfaction levels following learning through the CAI. The samples comprised 40 tenth-grade students, with 20 students each in the control and experimental groups, selected from Tha-Makham Wittaya School in Ratchaburi Province during the first semester of 2023 using purposive sampling. The research tools consisted of the following: 1) the CAI titled “Chemical Reaction and Equation” with an Index of Concordance (IOC) ranging between .67 and 1.00 2) the learning management plan of the CAI with IOCs between .67 and 1.00 3) the 5-level satisfaction questionnaire with IOCs of 1.00 and 4) a test designed to assess an academic achievement, with levels of internal consistency indicated by KR-20 of .70, including difficulty values ranging between .50 and .80 and discrimination levels ranging between .25 and .62. The results of this research revealed that
