A В Reaction progress Reaction pathway A is O exothermic. neither exothermic nor endothermic. O endothermic. Reaction pathway B is O endothermic. O exothermic. O neither exothermic nor endothermic. Which reaction pathway has the faster rate of reaction and why? O Reaction pathway A has the faster rate because the activation energy is greater than the activation energy of reaction pathway B. Reaction pathway A has the faster rate because the products have more energy than the products of reaction pathway B. O Reaction pathway B has the faster rate because the products have less energy than the products of reaction pathway A. Reaction pathway B has the faster rate because the activation energy is smaller than the activation energy of reaction pathway A.
