Multiple-choice question: At normal temperatures, NH4HCO3(s) can undergo the following decomposition reaction: NH4HCO3(s) = NH3(g) + CO2(g) + H2O(g). Suppose two sealed containers, A and B, with equal volumes are used; 1 kg and 20 kg of pure NH4HCO3(s) are placed in each container respectively, and both are kept at 298 K. After equilibrium is reached, which of the following statements is correct? ( ) A. The pressures in the two containers are equal. B. The pressure in container A is greater than that in container B. C. The pressure in container B is greater than that in container A. D. It is necessary to conduct actual measurements to determine which container has a higher pressure. Answer: A Hint: The answer can be seen in the response
