The estimated portion of light bulbs that last more than 500 hours will be
x=∑xn=224/430=0.521=52.1%
The activation energy for the forward and the one for the reverse
reaction are similar because they attained chemical equilibrium. A chemical
equilibrium happens when both of the reactant and products achieve the same
concentration.
265 x 0.06 = 15.9
265 - 15.9 = 249.1
249.1 is your answer
hope this helps
