Br, (aq) + HCO0Н (ад) — 2Br (aq) + 2H" (аq) + Со, (g) The reaction was monitored by measuring the volume of carbon dioxide produced as time progressed. o 5 10 15 20 25 [Source: © International Baccalaureate Organization 2019] 30 20 40 60 80 100 120 140 160 Time / s [Source: © International Baccalaureate Organization 2019] Determine from the graph the rate of reaction at 20 s, in cm³ s1, showing your working. 3b. Outline, with a reason, another property that could be monitored to measure the rate of this reaction. 3c. Describe one systematic error associated with the use of the gas syringe, and how the error affects the calculated rate. 3d. Identify one error associated with the use of an accurate stopwatch.

G what does it mea 1 / 2 100% Chemical Reactions-Write Neat and Balanced Reactions from Word Equations You need to submit one sheet of paper (not this one), that is very neat, with a fully balanced reaction for these 6 reactions Remember to include proper states. 1. solid potassium metal reacts with oxygen gas to produce solid potassium oxide. 2. solid potassium chlorate decomposes into oxygen gas and solid potassium chloride. 3. solid aluminum oxide is decomposed into solid aluminum and oxygen gas. 4. aqueous cobalt(III) nitrate reacts with solid zinc to produce aqueous zinc nitrate and solid cobalt.

A plot of 1NO21NO2 versus time is linear. Using this information, identify the factor by which the rate will increase in model (c) if the number of molecules is increased by a factor of 4.
