7.4 Case Study: The Haber Process: Ammonia for Food and Bombs From: Eros Wang To: Ms. Irumekhai Date: March 30‚ 2012 1. Suggest five factors that could affect the production of ammonia in the Haber process. Explain the effect of each factor‚ using rate theory. The Haber process itself is a delicate balancing act because of all the factors that affect the yield of ammonia. In the Haber process‚ the nitrogen‚ hydrogen and ammonia are in equilibrium. So five factors that affect the

Title:Extraction:Extraction with acid and alkaline Objective: 1. To recover benzoic acid and p-dichlorobenzene from its mixture using acid-alkaline extraction. 2. To determine the percentage recovery and melting point of benzoic acid and p-diclorobenzene. Apparatus:Separatory funnel(250mL)‚Buchner funnel‚beaker. Materials:Benzoic acid‚p-dichlorobenzene‚ether‚10% NaOH‚conc.HCl‚distilled water‚ anhydrous CaCl2. Introduction: Organic compounds in an aqueous mixture can be separated

The purpose of this experiment was to synthesize triphenylmethanol from a Grignard reagent. The Grignard reaction technique was used in this synthesis but due to the fact that it is such a strong nucleophile and base‚ it was important to prevent water from interfering with the Grignard reaction. Purity of the product was determined by measuring the melting point. Reagent Table: Structure Name Molecular formula Molar mass Density Melting point Boiling Point Diethyl ether C4H10O

average boiling points of the test tubes‚ 73°C and 162°C respectively‚ were compared to the boiling points in the tables of alcohols and ketones found in the back of the lab manual. Test tube two was comparable to methanol‚ ethanol‚ 2-propanol‚ and 2-methyl-2-propanol. Upon inspection of the IR spectrums‚ 2-propanol was a match.
