(a) Calculate the stoichiometric reactant ratio (mol H2 react/mol CH2 react) and the yield ratio (kmol C2H6 formed/kmol H2 react). (b) Determine the limiting reactant and calculate the percentage by which the other reactant is in excess.

WebA common way to determine the catalyst:limiting reactant ratio in a catalytic reaction is to report the amount of catalyst used in mol\%. For example, 5 mol% catalyst means that the reaction uses 5% as much catalyst as limiting reactant. Showing all your work, calculate the mol\% of P d used in this reaction where R and R′ = H. Web4.1.3 Effect of Solvent to Reactant SA Mass Ratio Solvent concentration also affects the reactions. In the early stage of the reaction, after 30 to 60 minutes, the SA conversion and the heptadecane yield steadily increased. With solvent to reactant SA mass ratios (sRatio) of 9:1 and 4:1 (i.e., high solvent application or low reactant

WebIt should be a one to two ratio, so we don't have enough carbon monoxide to react all of the hydrogen. So, carbon monoxide, carbon monoxide is limiting, limiting reactant. Now, given that this is the excess reactant, let's see how this, the, we can use stoichometric ratios to figure out how much methanol's going to be produced.

WebThe conversion ratio reaches a maximum at low concentration values, and rapidly decreases to an unmeasurable value at even lower concentrations where no reduced DCIP is detected.
