Question 11 X Incorrect. Isooctane, C3H18, is the basis of the octane rating system for gasoline because it burns smoothly, with minimal engine knocking. Pure isooctane is assigned a value of 100. Octane ratings are assigned to gasoline mixtures based on their ability to prevent knocking relative to isooctane. Estimate the energy released during the combustion of 1.00 mol of pure isooctane. Please note the combustion is exothermic process and the released energy is positive for the surroundings. -285.8 kJ

Chemical reactions occur when molecules or atoms collide in a way that the bonds between atoms break and new bonds form. Breaking the bonds of the reactants requires energy, whereas bond formation releases energy. Select the true statements regarding energy changes during a reaction. When the activation energy is high, the reaction rate is fast. If the heat of reaction, AH, is positive, the energy of the products is lower than the energy of the reactants and the reaction is exothermic. Decreasing the temperature decreases the kinetic energy of the reactants, and the reaction goes more slowly. The energy of a collision between atoms or molecules must be greater than or equal to the activation energy, Ea, for bonds to be broken. Increasing the concentration of reactants increases the number of collisions, and the reaction goes faster. Reactants must collide with proper orientation and with energy greater than or equal to the activation energy for a reaction to occur. The activation…

Given the enthalpy of formation data in the table below, what is the enthalpy of reaction for the reaction you performed in this lab? How does this compare to your experimental results? To calculate the enthalpy of reaction, use the formula below. AHran=EAH; (products) - EAH; (reactants) ΔΗ, Note that you will need the balanced chemical equation for the reaction performed in the lab, which can be found in the Background in your Hayden-McNeil course site. Also note that AHⓇ for standard state elements is 0 kJ/mol. Substance AH₁ (kJ/mol) MgCl₂(aq) -785.1 kJ/mol HCl(aq) -167.2 kJ/mol
