Calculating the reaction rate of one reactant from that of another Nitric acid is a key industrial chemical, largely used to make fertilizers and explosives. The first step in its synthesis is the oxidation of ammonia. In this reaction, gaseous ammonia reacts with dioxygen gas to produce nitrogen monoxide gas and water. Suppose a chemical engineer studying a new catalyst for the oxidation of ammonia reaction finds that 687. liters per second of dioxygen are consumed when the reaction is run at 158. °C and the dioxygen is supplied at 0.90 atm. Calculate the rate at which nitrogen monoxide is being produced. Give your answer in kilograms per second. Round your answer to 2 significant digits. kg S x10 ☑ ك Undo

The rate of a reaction is how quickly the reaction goes to completion. If two reactions have the same amount of reactant, increasing the rate does not increase the amount of product produced, it simply reduces the time that it takes to make the product. Using the internet, research the Reactant concentration factor below that affect the rate of a chemical reaction. 1. Reactant concentration (be very detailed add graphs to explain your details it should be 300 words) Your work should be written in complete sentences, and assume your audience is grade 11 chemistry students who do not understand this unit. Make sure all research is put into your own words!
