The reaction rate between two gases, A and B, increases by four as you double the concentration of gas A.  Doubling the concentration of gas B doubles the reaction rate.  The order of this reation would be described as:
a. first order with respect to A, and second order with respect to B
b. second order with respect to A, and first order with respect to B
c. first order with respect to A, and first order wth respect to B
d. fourth order wth respect to A, and second order with respect to B

b. A second order, B first order.
