The haze weather has been raging many times.

③(2 points) [The starting point is at the origin 0 (give 1 min), and the time to reach equilibrium is later than the equilibrium point of the curve "T 2, S 1" (give 1 min).

(2)① CH 4 (g) +N 2 O 4 (g) = N 2 (g) +CO 2 (g) +2H 2 O (g)? =-810.1kj mol-1(2 points)

② 2co2+2h2o2hcooh+O2 (2 points)? A→b (2 points)

Analysis of test questions: (1)② The reaction image shows that the reaction speed of TI curve is fast, the temperature is high, the carbon dioxide content is low and the reaction is exothermic; (3) The larger the surface area, the faster the reaction rate, but the catalyst does not change the equilibrium concentration, and the carbon dioxide concentration is the same at equilibrium; (2)① Equation 1 Subtract Equation 2 to get CH4 (g)+N2O4 (g) = N2 (g)+CO2 (g)+2H2O (g)? =-8 10. 1 kJ mol- 1； ② According to the schematic diagram of the battery, the reactants are water and carbon dioxide, and the products are formic acid and oxygen; Water loses electrons in catalyst A to generate oxygen. A is the negative electrode, and the direction of electron flow is A → B.
