(1) The positive reaction of this reaction is endothermic. With the increase of temperature, the equilibrium shifts to the positive reaction direction and the equilibrium constant increases.

So the answer is: increase;

(2) Remove all C, because it is a reversible reaction, carbon will be generated, and the generated carbon cannot completely react, so the balance moves to the left.

So the answer is: move to the left;

(3)① When the volume of the container decreases, the pressure increases, the instantaneous positive reaction rate accelerates, the equilibrium moves to the reverse reaction, and the positive reaction rate increases to a new equilibrium; (2) When the temperature is lowered, the instantaneous positive reaction rate slows down, the equilibrium reverse reaction moves, and the positive reaction rate increases to a new balance, so the image is:

So the answer is:

(4) According to Ⅰ, the equilibrium constant k=0. 1×0.60.06= 1, and Ⅱ is in equilibrium. According to the equilibrium constant, we can know that c(H2)=K in Ⅱ. c(H2O)c(CO)= 1×0. 120.2 = 0.6，

In ⅲ, the concentration quotient QC = 0.4× 0.20.1= 0.8 <1,so the reaction proceeds in the positive direction, so ν is positive > ν is negative.

So the answer is: 0.06; >;

(5) The anode of the primary battery undergoes a reduction reaction, and oxygen is discharged at the anode. By using the proton exchange membrane, hydrogen ions generated at the cathode move to the anode, so oxygen is discharged at the anode to generate water. The electrode reaction formula is O2+4h+4e-= 2h2o. The essence of a galvanic cell is that methanol burns to generate carbon dioxide and water, so the total reaction formula is 2CH3OH+3O2=2CO2+4H2O.

So the answer is: O2+4h+4e-= 2h2o; 2CH3OH+3O2=2CO2+4H2O。
