1. The rate of a chemical reaction usually varies with 1. concentration. 2. time. 3. temperature. 4. catalyst. a. 1 only d. 1, 3, and 4 b. 1 and 3 only e. 1,2,3, and 4 c. 3 and 4 only 2. When 100ml of 1.0MHCl is added to 2g of Na2CO3 crystals, carbon dioxide is evolved. Na2CO3(s)+2HCl(aq)"2NaCl(aq)+CO2(g)+H2O(l) All of the following will increase the initial rate of the reaction EXCEPT a. addition of 100mL of 2.0MHCl instead of 1.0MHCl. b. addition of 200mL of 1.0MHCl instead of 100mL. c. addition of 100mL of 1.0MHCl to powdered Na2CO3 instead of crystalline Na2CO3. d. addition of 100mL of hot 1.0MHCl instead of 1.0MHCl at room temperature. e. addition of 200mL of 2.0MHCl instead of 100mL of 1.0MHCl. 3. Calculate the average rate or reaction a) Between 0&1hr b) Between 1&2 hrs Figure 1: Concentration versus Time for the reaction 2N2O5(g)4NO2(g)+O2(g) c) Which one is larger
