# Chemistry rate of reactions

I have a chemistry exercise and I am not really sure if I have solved it correctly.

During the mixing of gaseous substances D and G, the elementary chemical reaction occurs:

2D+G->2C+B

After some time from the start of the reaction, the transformation of the substances became:

[D]=4 mol/I,[G]=2 mol/,[C]=3.2 mol/l

Calculate:

a) initial concentration of substances

b) the initial speed if the speed determination is 0.5. l^2*mol^-2*s^-1
c)argument how the speed of the chemical reaction changes with the increase of the effective hits of the reactants
