Question 19

Figure 1 shows an incomplete reaction profile for the thermal decomposition of calcium carbonate, which is an endothermic reaction.

An incomplete reaction profile diagram with 'Energy' on the vertical axis and 'Progress of reaction' on the horizontal axis. A horizontal line representing the reactant, calcium carbonate, is shown on the left. A higher horizontal line representing the products, calcium oxide + carbon dioxide, is shown on the right. There is a blank gap between these two energy levels.

Complete the reaction profile in Figure 1 and label the activation energy (EaE_aEa​).
