ClO(g)→Cl2(g)+O2(g) (unbalanced) Using the following experimental data, three different graphs were created including a linear regression on each of them: Q 1(a) i. Balance the chemical equation. [5 Marks] ii. What is the overall order of reaction? iil. Determine the rate law for the reaction. Q 1(b) [10 Marks] i. Write down the integrated rate law for this reaction. ii. Using the information from the adequato linear regresision, calculate the initial concentration of ClO radical and the rate constant of the reaction. iii. Determine the half-life of a ClO radicar. Iv. Calculate the concentration of ClO radigat after 15 ms. Q1(c) [10 Marks] Methane is one of the main greenhouse gases involved in the global warming. The main path by which CH4 is removed from the lower atmosphere is the reaction with the hydroxyl radical. The pre-exponential factor and the activation energy for this reaction are A=1.13×109Ms−1 and Ea=14.1 kJ mol−1 respectively. i. Write down the chemical reaction between methane and hydroxyl radical to form water and methyl radical. ii. Is it possible to determine the overall order of reaction? If the answer is yes. indicate the overall order of reaction. iii. Calculate the rate constant at 20∘C. iv. What would happen to the rate constant, if the tehmerature increases? i. Roughly sketch and label an Arrhenius graph for this reaction (ln(k)vsT−1). Indicate the meaning of the slope and the intercept in the graph.
