how do i do these two questions? Assume that the reaction: CO(g) + H2O(g) = CO2(g)...
The activation energy for the reaction NO2(g)+CO(g)⟶NO(g)+CO2(g) is Ea = 200 kJ/mol and the change in enthalpy for the reaction is ΔH = -200 kJ/mol . What is the activation energy for the reverse reaction?
The activation energy for the reaction NO2(g)+CO(g)⟶NO(g)+CO2(g) is Ea = 150 kJ/mol and the change in enthalpy for the reaction is ΔH = -375 kJ/mol . What is the activation energy for the reverse reaction?
The reaction NO2(g) + CO(g) CO2(g) + NO(g) has a rate constant of 2.57 M−1∙s−1 at 701 K and 567 M−1∙s−1 at 895 K. Find the activation energy in kJ/mol
You have the following reaction: NO2 (g) + CO (g) ⟶ NO (g) + CO2 (g) The rate constant (k) at 701 K is 2.57 M-1s-1. If the activation energy is 150 kJ/mol, what is k at 895 K? R = 8.314 J/(mol*K) A) 680 M-1s-1 B) 443 M-1s-1 C) 2.58 M-1s-1 D) 0.950 M-1s-1 E) 6.52 M-1s-1
For the reaction CO(g) + H2O(1)—*CO2(g) + H2(g) AH° = 2.8 kJ and AS° = 76.8 J/K The standard free energy change for the reaction of 2.33 moles of CO(g) at 288 K, 1 atm would be kJ. This reaction is (reactant, product) favored under standard conditions at 288 K. Assume that AH° and ASº are independent of temperature.
