The answer depends on whether or not the reaction is endothermic or exothermic.

How are you measuring the CO2? CO2 is less soluble in warm than in cold solution so if measuring the gas in solution it will be less. If measuring the gas tha leaves the solution it should be greater at the higher temperatures.

I am measuring it in solution by an eudiometer so when we warm the HCl we then add the chalk and then we immediately collect the CO2 produced using an eudiometer and a tube that collects it. But I’m not sure how to explain that using chemistry because each time we increased the temperature of HCl , less CO2 was produced (In the span of 20 seconds)

If the reaction is exothermic, your results make sense as heat would be a product of the reaction. (See Le Chateliers principle). You can look up to see if it is an exothermic reaction.

We used a hot water bath to warm up the flask with HCl and we used a theormometer to measure the temperature.01/19/19
