Li-MgO is a typical catalyst for the oxidative coupling of methane (OCM) reaction, one of the most challenging reactions in heterogeneous catalysis. Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide).It has an empirical formula of Mg O and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding. In a chemical reaction a. The reaction kinetics of MgO could be described using α = 1 − e−k*t. For b) we notice MgO is a product in our reaction, therefore reverse the equation, the coefficient is 1 since there is one mol MgO product Mg2 + (aq) + 2Cl - (aq) + H2O (l) → MgO (s) + 2HCl (aq) We can notice that HCl is not a product in our final reaction, so we want to cancel it. The dehydration rate and heat storage rate of Mg (OH) 2 at 270 °C notably increases by factors of 222 and 92, respectively. This reversible reaction can be expressed with the following equation : (1) M g (O H) 2 + Δ H ⇌ M g O + H 2 O, Δ H = 81 k J / m o l. Magnesium hydroxide is cheap and abundant.
