Is the trend in reactivity for nonmetals the same as the trend in reactivity for metals?

no

Explanation:

In Non-metals

Period - reactivity increases as you go from the left to the right. Group - reactivity decreases as you go down the group

In Metals

Reactivity increases down a group because as nuclear shielding increases and the nucleus' hold on the valence electron weakens, therefore it is easier to remove valence electrons.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

a electronegativity decreases beacuse the size of nucleus is bigger.
