Calcium carbonate decomposition

Figure 1 shows the calcium carbonate decomposition in N 2 at three different heating rates: the left graph uses the x-axis for the temperature, and the right graph for time. Modifying the heating rate leads to a shift in the temper-ature range where the calcium carbonate decomposition takes place. Higher rates correspond to broader temperature
