115. Solving a chemistry problem

53. The reaction C (graphite) 2F2 (g) \u003d CF2 (g) is given.
Write down the kinetic equation of the reaction and determine its theoretical order. Determine how the reaction rate will change (how many times it will increase or decrease): a) with an increase in the concentration of F2 by 4 times; b) when the temperature decreases by 20 degrees, considering the value of the temperature coefficient of the reaction rate to be 4.
