Imagine that it takes 8 minutes to cook pasta to your desired level at a sea level location where atmospheric pressure is 1.00 atm. At a much higher altitude location water boils at 89oC, and it takes 14 minutes to cook the pasta to the same level. What is the "activation energy" associated with cooking the pasta? a. 30 kJ b. 30 J c. 50 J d. 50 kJ

    The equation is solved below

    Explanation:

    According to Arrhenius equation, K = A*e-Ea/RT, where A is a constant Hence, ln K = ln (Ae-Ea/RT) ln K = ln A - Ea/RT

    Where

    k is the rate constant

    A is an exponential factor that is a constant for a given chemical reaction, relating the frequency of collisions of particles

    Ea is the activation energy of the reaction (usually given in Joules per mole or J/mol)

    R is the universal gas constant

    T is the absolute temperature (in Kelvins)

    k = Ae-Ea/RT

    1.0 x 10-10 s-1 = Ae (-111 kJ/mol) / (8.314 x 10-3 kJ mol-1K-1) (300K)
