Combustion reactions are assumed to follow the arrhenius rate equation. w = a.[fuel][c where w is the overall reaction rate, a, is the pre-exponential factor, [fuel] is the fuel concentration, [02] is the oxygen concentration, ea is the activation energy, r is the universal gas constant, and t is the absolute temperature. [10 points] i. ii. how does the reaction rate change if the pressure is halved? air has an approximate oxygen concentration of 21% by volume. how would the reaction rate change if the oxygen concentration is increase to 50% by volume? assume all other values remain constant. explain which term is more dominant in the arrhenius rate equation.
