Determine the effectiveness factor for a nonisothermal spherical catalyst pellet in which a first-order isomerization is taking place. additional information: a_i = 100 m^2/m^3 -delta h_r = 800,000 j/mol c_as = 0.01 kmol/m^3 k_t = 0.004 j/m middot s middot k dp = 0.005 m k_1 = 10^-1 m/s e = 100,000 j/mol ts = 400 k de = 8 times 10^-8 m^2/s how would your answer change if the pellets were 10^-2, 10^-4 and 10^-5 in diameter? what are typical temperature gradients in catalyst pellets?

h

it is stable as it is in group 0 which have full outer shells of electrons

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
