Exercise 1 - Questions Question 1 Use your results to determine if the forward reaction in the potassium chromate/HCI reaction endothermic or exothermic. Explain your answer, using the table below to help construct your thoughts. Type of Change Increase concentration of reactant OR Decrease concentration of product Decrease concentration of reactant OR Increase concentration of product Increase temperature of an exothermic reaction Increase temperature of an endothermic reaction Decrease temperature of an exothermic reaction Decrease temperature of an endothermic reaction Decrease pressure (gases only) Increase pressure (gases only) Chemical System Shift (Right shifts toward product. Left Shifts toward reactant.) Right Left Left Right Right Left Toward the side with more gas molecules Toward the side with less gas molecules Question 2 $2CrO_4^{2-}(aq) + 2H^+(aq) \rightleftharpoons Cr_2O_7^{2-}(aq) + H_2O(l)$ Write the equation for the equilibrium constant (K) of the reaction studied in this exercise. Question 3 Consider the chemical reaction: N$_2$ + 3H$_2$ yields 2NH$_3$. If the concentration of the reactant H$_2$ was increased from 1.0 x 10$^{-2}$ M to 2.5 x 10$^{-1}$ M, calculate the reaction quotient (Q) and determine which way the chemical system would shift by comparing the value of Q to K.

A 20.0 g sample of iron at a temperature of 75.0°C is submerged in a 30.0 g sample of water held at a temperature of 4.00°C. What will the final temperature of this mixture be some time later? (The specific heat capacity of iron is cFe = 0.450 J/g°C and for water it is cw = 4.19 J/g°C for reference)
