To answer this question, the temperature values for each time interval in Table 1 are required. The provided table is incomplete, as it does not contain any temperature readings. Therefore, I cannot plot the graph or determine the temperature change without the necessary data. Here's how you would approach the problem if the data were available: a) Plot the graph of temperature against time: The x-axis would represent Time (min) and the y-axis* would represent Temperature (^c). You would plot the given temperature values against their corresponding time points. The procedure states that solid A is added at 2(1)/(2) minutes. The graph would typically show an initial stable temperature, followed by a sharp change (increase or decrease) after 2(1)/(2) minutes as the reaction occurs, and then a gradual return towards room temperature. Draw a smooth curve through the plotted points. b) Using the graph determine the temperature change: From the graph, extrapolate the initial temperature of the hydrochloric acid at the time of mixing (e.g., at 2(1)/(2) minutes, before the reaction fully takes effect, by extending the initial temperature line). Extrapolate the maximum or minimum temperature that would have been reached if no heat was lost to the surroundings (by extending the cooling/heating curve back to the time of mixing). The temperature change, T, would be the difference between this extrapolated maximum/minimum temperature and the initial temperature. Since the data is missing, a numerical answer cannot be provided.
