Consider the data presented in Exercise 14.19. (a) By using appropriate graphs, determine whether the reaction is first order or second order.

Step 1 of 5) All the water on Earth is connected in a global water cycle (Figure 18.16). Most of the processes depicted here rely on the phase changes of water. For instance, warmed by the Sun, liquid water in the oceans evaporates into the atmosphere as water vapor and condenses into liquid water droplets that we see as clouds. Water droplets in the clouds can crystallize to ice, which can precipitate as hail or snow. Once on the ground, the hail or snow melts to liquid water, which soaks into the ground. If conditions are right, it is also possible for ice on the ground to sublime to water vapor in the atmosphere. Because the processes occurring on the surface (evaporation, sublimation) are endothermic and those occurring in the atmosphere (condensation, crystallization) are exothermic they act to transfer heat absorbed by the surface into the atmosphere.
