97. Solving a chemistry problem

49. The reaction CO2 (g) ZH2 (g) \u003d CH3OH (l) H2O (g) is given.
Write the kinetic equation for the reaction and determine its theoretical order. Determine how the reaction rate will change (how many times it will increase or decrease): a) with a 2-fold increase in pressure; b) when the temperature decreases by 40 degrees, considering the value of the temperature coefficient of the reaction rate equal to 2
