You're on a roll — i) To determine the rate of reaction at 12 minutes: Step 1: Locate the point on the curve corresponding to 12 minutes on the time (x-axis). Step 2: Draw a tangent to the curve at this specific point. Step 3: Calculate the gradient (slope) of this tangent. The gradient, Total volume of oxygen Time, represents the rate of reaction at 12 minutes. ii) The production of oxygen in region A_1B_1 is faster than in region B_1C_1. Explanation: In region A_1B_1, the concentration of reactants is higher, leading to a greater frequency of effective collisions between reactant particles and thus a faster rate of reaction. As the reaction proceeds into region B_1C_1, the concentration of reactants decreases, resulting in fewer effective collisions and a slower rate of oxygen production. iii) The equation for the decomposition of hydrogen peroxide is: 2H_2O_2(aq) 2H_2O(l) + O_2(g) c) i) A major source of nitrogen gas in the Haber process is air.
