Given the following balanced equation, determine the rate of reaction with respect to [SO2]: 2SO2 (g) + O2 (g)......yields..... 2SO3 (g)
a. Rate = -1/2 delta SO2 over delta t
b. Rate = +1/2 delta SO2 over delta t
c. Rate = -delta SO2 over delta t
d. Rate = +2delta SO2 over delta t
e. it is not possible to determine without more information
