Question
Use your results to determine if the forward reaction in the potassium chromate/HCl reaction is endothermic or exothermic. Explain your answer using Table 1 to help construct your thoughts.
Thank you!
Data Table 1: Chromate-Dichromate # of HCI Drops to Reach Equilibrium # of NaOH Drops to Shift Equilibrium Position 12 Color of Dichromate Color of Chromate Yellow Orange Data Table 2: Endothermic and Exothermic Equilibrium Position Reaction to Room Temperature Blood Orange Reaction in Cold Water Bath Bright Orange Left shift - toward the reactants Reaction in Hot Water Bath Blood Orange Right shift towards the product Color: Equilibrium Position: (Left or Right) Explanation of why equilibrium is shifted to the left or to the right There were solidThe solution was particles on the 100% liquid. There were no solid particles, which means that the reactants mixed together to form a product. bottom of the pipet while the liquid maintained the majority of the pipet. So there was a solid potion an d a liquid portionExplanation / Answer
The Reaction is Endothermic.
decrease in temperature making the reaction towards left is Endothermic.
Increase in temperature making the reaction towards right is Endothermic.
