<![CDATA[This research aims to describe the feasibility of Electronic Student Worksheet Inquiry with Multiple Chemical Representations to Train Students' Critical Thinking Skills on Reaction Rate Material. The feasibility of e-worksheet is reviewed in terms of validity, practicality, and effectiveness. This research uses the Research and Development (R&D) method with the ADDIE model limited to the development stage. A limited trial was conducted in January 2024 on 32 students who received reaction rate material. The research results showed that the validity of the e-worksheet was declared valid based on the criteria for content validity getting mode four and construct validity getting mode 3. The practicality of e-worksheet was declared practical based on the results of the student response questionnaire, which showed a percentage of 98.4%. e-worksheet was declared effective based on the t-test results with a significance level 0.05, resulting in a t count of 68.50. Based on these results, it can be concluded that e-worksheet is suitable for use in practicing critical thinking skills on reaction rate material.]]>
