The difficulty of students in understanding chemistry is marked by the inability of students to solve chemistry problems in the form of concepts and chemical calculations correctly. The purpose of this research was to find out the students conceptual and algorithms errors in solving chemistry problems on the subject of thermochemistry and the relationship. Data analysis technique using qualitative data analysis. The research was conducted at SMA N 3 Tanjungpinang with the population being class XI MIPA.  The subjects of this study were 25 people in class XI IPA. The technique used in this research is by spreading essay tests.
