Ethanol is produced by the following reaction at atmospheric pressure: c2h5 oh () c2h4 (g)h20 (g) c as an the reactants enter the reactor at 250 equimolar mixture (1 mol of each reactant), and liquid ethanol leaves the reactor at 332.8 k. how much heat needs to be removed from the reactor per mol of ethanol formed, if the reaction goes to completion? give your answer as a positive value, in kj to 1 decimal place data given: enthalpy change for reactants from 523.15 k to 298.15 k =-20051 heats for formation for c2h4 (g), h20 (g) and c2h50h are 52510, -241,818 and -277,690 j/mol respectively (1) take r 8.314 j/mol-k. = for ethanol, a, b and c are 3.518, 0.02001 and -6.002 x 10 6 respectively in the following function: cp -a + bt +ct2 r

Consider a culture medium on which only gram-positive organisms such as staphylococcus aureus colonies can grow due to an elevated nacl level. a yellow halo surrounds the growth, indicating the bacterium fermented a sugar in the medium, decreasing the ph as a result and changing the color of a ph indicator chemical. this type of medium would be referred to as a differential and enrichment culture.
