Q.2-I completted Parts A,B,C. i need help with part D
The synthesis of methanol from carbon monoxide and hydrogen gas is described by the following chemical equation: CO(g) + 2H (8) CH, OH(g) The equilibrium constant for this reaction at 25°C is K -2.3 x 104. In this tutorial, you will use the equilibrium constant expression to find the concentration of methanol at equilibrium, given the concentration of the reactants. Part A Determine the expression for the equilibrium constant, K,...

I. Write the equilibrium constant expression, K for the following reaction Fe"(ag) FENCS(ag) SCN (ag) + CFENCS D 2. In part A of Experiment 34, it was assumed that all of the SCN added to the reaction mixture was converted to product (FeNCS). Which of the following best explains why that assumption was valid? A) The moles of Fe added equaled the moles of SCN- added. B) In part A, the SCN was the limiting reactant whereas in part B,...
