26. Solving a chemistry problem

1. Given the reaction 2FeO(k) 2SO2(r)=2FeS(k) 3O2(r), write down the kinetic equation of the reaction and determine its theoretical order. Determine how the reaction rate will change (by how many times will it increase or decrease): a) when the volume decreases by 3 times b) when the temperature decreases by 30 degrees, considering the value of the temperature coefficient of the reaction rate to be equal to 4.
