66. How will the rate of some chemical reaction change if the temperature of the system changes in the range Δt ° at the temperature coefficient of the rate γ. (column 2)
2. Write an expression for the law of mass action for direct and reverse reactions (taking into account the possibility of the presence of heterogeneous systems). (column 3)
3. How many times and how will the rate of a chemical reaction (forward or reverse) change with a change in concentrations and pressure in the system. (column 4)
4. Formulate a principle that describes the direction of displacement of chemical equilibrium. In which direction and why will the equilibrium shift in these cases? (column 5)
5. Calculate the value of the chemical equilibrium constant for the specified system, if the concentrations of all gaseous substances are the same and equal to the specified value. (column 6)
No.
boil
anta Δt, 0C and γ Equilibrium of the system and sign of enthalpy change How many times and how will the reaction rate change equilibrium shift as a result of: Concentration values, mol/l
66 from 850 to
1150 at γ= 3.4 C2H5OH (g) 3O2(g)↔ 2CO2(g) 3H2O(g); ∆H<0
(1)

FeO (cr) H2(g) ↔ Fe(cr) H2O(cr); ∆H>0
(2) Direct (scheme 1) with an increase in the concentration of the initial substances by 2 times, and reverse (scheme 2) with an increase in pressure in the system
4 times Temperature increase in the system (1); reduce system pressure(2) 1.1
