120. Solving a chemistry problem

The reaction W(c) 3H2O(g)=WO3(c) 3H2(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 volume by 2 times; b) with an increase in temperature by 30 degrees, considering the value of the temperature coefficient of the reaction rate equal to 3.
