5.7: Using Graphs to Determine Integrated Rate Laws

WebFeb 12, 2024 · Thus, the equation of a straight line is applicable: ln[A] = − kt + ln[A]o. To test if it the reaction is a first-order reaction, plot the natural logarithm of a reactant concentration versus time and see whether the graph is linear. If the graph is linear and has a negative slope, the reaction must be a first-order reaction. WebThe overall chemical equation says that 1 mole of glucose reacts with 6 moles of oxygen gas for the reaction to occur. So the glucose to oxygen ratio is 1:6, or basically we need 6 times as many moles of oxygen gas as we do glucose for the reaction to happen. So 0.129 x 6 = 0.833 moles of oxygen. Hope that helps. harlands accounting bloomington il
