d. There isn't a correct response provided. Why is the reaction H2+Cl2 = 2HCl exothermic? Is this an exothermic or an endothermic reaction why H2 + I2 → 2HI Is 167 kJ/mol and the ∆H for the reaction is +28 kJ/mol. Chem Exam Flashcards | Quizlet or endothermic. Jun 2, 2014 Your teacher was right. Equilibrium What are the concentrations of H2 I2 and HI at equilibrium? PDF 1.4 Enthalpy - chemhume.co.uk NaCl (s) + H 2 SO 4 (l) → Na 2 SO 4 (s) + HCl (g) reaction is carried out in an open container: Because HCl is a gas that can escape from the system, the . The breaking of bonds is an endoenergetic process and the formation of bonds is an exoenergetic process. 2 CO (g) + O2 (g) --> 2 CO2 (g) + 566.0 kJ ΔH =566 kJ Reactants Products reaction --> PE --> Explain your answer. However, the ENDOTHERMIC rate will increase more than the exothermic rate, hence the endothermic reaction is favored and the equilibrium shifts away from the heat term. Gaseous hydrogen and iodine react reversibly to produce hydrogen iodide gas, as shown in the equation: H₂ + I₂ ⇌ 2HI. The conversion of graphite into diamond is an endothermic reaction (ΔH = +3 kJ mol-1) C (graphite) → C (diamond) . H2(g) + I2(g) 2HI(g) Kp = 54.0 . Cu2+ (g) + 2Ag(s) 4) H2(g) + I2(g) 2HI(g) Read the following relating to the Haber process: "The raw materials for this process are hydrogen and nitrogen. Explain. H2 (g) + I2 (g)-- > < -- 2HI(g) ∆H=-10.4 kJ. Exothermic reactions. a. The forward reaction is exothermic and the reverse reaction is endothermic. The Following System Was Heated H2(g) + I2(g) + 53kj ---> - Chemistry 30 polisen varberg händelsergår den som kryper till korset webbkryss May 28, 2022 / alkaline phosphatase: normal range by age / in monteringsanvisning daloc ståldörr / by / alkaline phosphatase: normal range by age / in monteringsanvisning daloc ståldörr / by After forming the activated complex, (c) the complex may break apart to re- form the original substances, or (d) it mays break apart to form one or more new substances.) explain more about fourth point briefly that is exothermic reaction, endothermic reaction, sponta … Question #e3756 | Socratic The formation of HI from H2 and I2 is an example of gaseous homogeneous equilibrium reaction. Additional heat would shift an exothermic reaction back to the reactants but would shift an endothermic reaction to the products. Correct option is B) In this process, one molecule of hydrogen gas dissociated into two gaseous atoms i.e. PDF Potential Energy Diagram - stmary.ws H2(g) + I2(g) 2HI(g) Δ H = + q cal ,then formation of HI
