If the decomposition of HBr (g) into H2 (g) and Br2 (g) is known to be second order with respect to HBr. Write a balanced chemical equation for this reaction. Write the rate law for this reaction. When the concentration of HBr is 2.0 M‚ the rate of decomposition is 1.58x102 M/s. Calculate the value and units of the rate constant. What is the rate of this reaction when the concentration of HBr is 0.75 M? Balance reaction: 2HBr (g) H2 (g)+ Br2 (g) Rate law reaction: K2 (HBr)2 Rate Constant: K2(1

they produce them and for whom they are produced’ (p.2). In questions 1 to 2 we consider how economics helps understand business and in question 3 we turn our attention to a brief history of management as published in Harvard Business Review (HBR) in 2012. HBR is one of the world’s most prestigious journals devoted to management. The paper is particularly useful as it highlights the ways that economic reasoning has influenced management thinking in the last century. Indeed‚ as the article suggests

first three parts of the Cyclohexanol Cycle. The cyclohexanol was first converted to cyclohexene and water by simple distillation (product: 6.5395g‚ 79.75% recovery). The cyclohexene then underwent a bromination reaction by addition of concentrated HBr and a 30% H2O2 solution‚ followed by an extraction of the aqueous phase. This produced trans-1‚2-dibromocyclohexane (product: 12.8886g‚ 67.34% recovery). The trans-1‚2-dibromocyclohexane was reduced by zinc metal to cyclohexene. The reaction was conducted

Bromination of trans- Stilbene to form 1‚2- Dibromo- 1‚2-diphenylethane Abstract 1‚2-dibromo-1‚2-diphenylethane was produced by the bromination of trans-stilbene through the addition of hydrobromic acid (HBr) and hydrogen peroxide (H2O2). This experiment was a greener bromination of stilbene because bromine was generated in situ and ethanol was used as the solvent. The melting point (243.30°C)‚ mass (.427g)‚ and percent yield (45.54) of the crystals were recorded. The FTIR
