A compound X undergoes 2 simultaneous first-order reactions as follows X-> Y with rate constant K1 and X->Z with rate constant K2. The ratio of k1/k2 at 40°C is 7.5. What is the ratio at 260°C? Assume the frequency factors of the 2 reactions are the same.

The correct answer is d

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.
