Please help with question 4&5
4.(2 pt) Hydrogen and carbon monoxide react to give formaldehyde, under certain conditions. CO (g) HCHO (g) H2 (g) The mechanism proposed for this reaction is: + â H+ CO â HCO H + HCO â HCHO Which of the following rate laws is consistent with this mechanism (and would be allowed)? EXPLAIN THE step 1. fast, reversible step 2. slow step 3. fast REASONS FOR YOUR CHOICE. (No credit will be given if there is no explanation.)rate? e) KIHI[HCO] Explanation: 5. (I pts) (a) Show by calculation if the following gas phase reaction is at equilibrium, with the molar concentration conditions stated under each participant. (Hint:Q reaction quotient). For this temperature, Keq= 1.45 x 104 4NHs + 502 ë·° 4N0 + 6H20 Instantaneous concentrations, M: 5.4 x 10 4.5x 10 2.3 x 10 9.7x 10 (b) (0.5 pt) Based on your calculation in part (a) what will be observed over time, in the reaction vessel? Circle one: more NO will form more NHs will form no change
