The reaction is: The reaction is an exothermic equilibrium reaction in which the gas volume is reduced. The equilibrium constant Keq of the reaction (see table) is obtained from: Since the reaction is exothermic, the equilibrium of the reaction shifts at lower t… WebMar 30, 2024 · 1 Introduction. Ammonia (NH 3) is an essential feedstock for nitrogen-based fertilizers and pharmaceuticals. [] Nowadays, the unsustainable Haber–Bosch technique is extensively utilized to synthesize over 90% NH 3 worldwide. Nevertheless, the extreme inertia of N 2 causes harsh reaction conditions (400–450 °C and 15–25 MPa), leading to … WebMar 26, 2013 · Relative fold change or relative expression was calculated by the delta delta Ct method. Delta Ct is the Ct value for the sample (control/experimental) normalized to the endogenous housekeeping gene (18S rRNA). Delta delta Ct was calculated by subtracting delta Ct of the calibrator or control sample from that of the experimental sample. sérum thicker de lazartigue
