When heated calcium carbonate decomposes according to the equation below. CaCO3(s) → CO2(g) + CaO (s)

In a study of the decomposition of calcium carbonate, a student added a 25.0 g sample of powdered CaCO3(s) into a rigid 2.0 L container. The student sealed the container, pumped out all the gases, then heated the container in an oven at 1100 K. As the container was heated, the total pressure of the CO2in the container was measured over time. The data are plotted in the graph below.

The student repeated the experiment but this time the student used a 50 g sample of powdered CaCO3(s). In this experiment, the final pressure in the container was 1.04 atm, which is the same final pressure as in the first experiment.

g. After 20 minutes some CO2, was injected into the container and initially raising the pressure to 1.5 atm. Would the final pressure inside the container be less than, greater than, or equal to 1.04 atm? Explain.
