4. A reaction occurs when one molecule of A collides with one molecule of B: A+B Product In the containers below, A molecules are shown as black dots and B molecules are shown as open dots. Each dot represents a mole of molecules: A B=0 The contents of the 4 containers are at the same temperature. The volumes of the containers are provided along the top. 2.0 L 2.0 L 1.0 L 0.5 L #1 #2 #3 #4 In which container above would the rate of reaction of A+B Product be the fastest? (A) Container #1 (B) Container #2 (C) Container #3 (D) Container #4
