Why, when solving for the rate, is [B] squared?

[Caroline LaPlaca]

No, cause its not like the K concentration thing.

[Johann Park 2B]

With respect to [B], the reaction is second-order. You use the different values for the rates and concentrations to solve for the exponents (x, y, z) on the concentrations.

[OliviaShearin2E]

Johann is right but to be clearer, first order in B means that the rate is proportional to , second order in B means that the rate is proportional to . and third order in B means that the rate is proportional to .

[Sandhya Rajkumar 1C]

The reaction is second order with respect to B because when the amount of B is doubled (increased by a factor of 2), the rate increases by a factor of 4, so instead of it being a 1:1 ratio, which would make it first order, it's a 1:2 ratio, which makes it second order.
