2A+2Bproducts rate=[B]

What is the order with respect to A? What is the order with respect to B? What is the overall reaction order?

The chemical reaction shown was performed and the concentration of CCl4CCl4 was measured over time.

Cl2(g)+CHCl3(g)HCl(g)+CCl4(g)Cl2(g)+CHCl3(g)HCl(g)+CCl4(g)

The [CCl4] after 7s was 0.049 mol/L. After 134s, the [CCl4] was 0.463 mol/L . Calculate the rate of reaction.
