Test analysis: (1)① The reaction is exothermic.

② According to the balance constant formula:

③ As can be seen from the image, V (CO2) = 0.05 mol/(L s), and according to the equation V (N2) = "0.025" mol/(L s).

④ The catalyst does not change the time to reach equilibrium.

⑤ The system is insulated and its volume is unchanged, indicating that there is no energy exchange with the outside world. With the progress of the reaction, the heat of the system will increase.

B with the increase of reaction temperature, the equilibrium moves to the left, and the k value decreases.

D, when the mass fraction of NO remains unchanged, it means that equilibrium is reached.

(2) According to Gaith's law: CH4 (g)+N2O4 (g) = = N2 (g)+2H2O (g)+CO2 (g) △ h =-898.1kj/mol.
