3. Determine the molecular formulas for a compound that gives the following percentages on analysis (in the mass percents) (10 %) 71.65 % for Cl, 24.27% for C, 4.07% for H, The molar mass is known to be 98.96 g/mol. (The atomic mass of C is 12.01, H is 1.008, Cl is 35.45)

10. For the reaction between nitric oxide and hydrogen, 2NO(g) + H2(g) →N2O(g) + H2O(g) may proceed via the following mechanism: 1. 2NO \(\xrightarrow{k_1}\) \(\xleftarrow{k_{-1}}\) N2O2 2. N2O2 + H2 \(\xrightarrow{k_2}\) N2O + H2OWrite the rate law for this reaction by using the steady-state approximation if step 2 is the rate-determining step in this mechanism. (10 %)
