Given the following rate law,

rate = k[A]²[B]

if [A] were doubled, what must happen to [B] to keep the rate constant?

• [B] must quadruple

• [B] must double

• [B] must be havled

• [B] must be quartered

The following data were measured for the reaction

BF₃(g) + NH_3(g) ⟶ F₃BNH_3(g)

What is the rate law for the reaction?

• rate = k[NH₃]

• rate = k[BF₃]²[NH₃]

• rate = k[BF₃][NH₃]

• rate = k[BF₃][NH₃]²

What is the rate law for this mechanism?

• rate = k[A][B]²

• rate = k[B][X]²

• rate = k[A]^0.5[B]^1.5

• rate = k[W][Y][Z]

What is the theory which explains how chemical reaction occurs?

• Diffusion 
• Collision

• Big Bang

• Evalusion

What letter represents the activation energy?

• A

• B

• C

• D

•  Adding an inert gases to the mixture

• Adding more NO₂ to the reaction mixture

• Increasing the temperature of the reaction vessel

• Decreasing the volume of the reaction vessel
