कौनो रासायनिक प्रतिक्रियाके प्रतीकात्मक निरूपणके रासायनिक समीकरण कहल जाहे ।
एकरा समीकरण एहीला कहल जाहे कि एकरामे समता चिन्ह (=) के प्रयोग कैल जाहे (= के स्थान पर →ओ के प्रयोग कैल जाहे) । समता चिन्हके बामा दन्ने क्रिया करेवाला अभिकारक लिखल जाहे आउ एकरा दहिना दन्ने उत्पाद लिखल जाहे । समीकरणके अधार ई हे कि कौनो रासायनिक प्रतिक्रियामे भाग लेवेवाला विभिन्न तत्वके परमाणुके सङ्ख्या प्रतिक्रियाके उपरान्तो अपरिवर्तित रहहे ।
सबसे पहिले रासायनिक समीकरण द्वारा रासायनिक प्रतिक्रियाके निरूपण बरिस १६१५ मे जीन बेग्विन कैलन ।

- ↑ The notation was proposed in 1884 by the Dutch chemist Jacobus Henricus van 't Hoff. See: Template:Wp/mag/Cite book Van 't Hoff called reactions that didn't proceed to completion "limited reactions". From pp. 4–5: "Or M. Pfaundler a relié ces deux phénomênes … s'accomplit en même temps dans deux sens opposés." (Now Mr. Pfaundler has joined these two phenomena in a single concept by considering the observed limit as the result of two opposing reactions, driving the one in the example cited to the formation of sea salt [i.e., NaCl] and nitric acid, [and] the other to hydrochloric acid and sodium nitrate. This consideration, which experiment validates, justifies the expression "chemical equilibrium", which is used to characterize the final state of limited reactions. I would propose to translate this expression by the following symbol: HCl + NO3 Na NO3 H + Cl Na . I thus replace, in this case, the = sign in the chemical equation by the sign , which in reality doesn't express just equality but shows also the direction of the reaction. This clearly expresses that a chemical action occurs simultaneously in two opposing directions.)
