Observe: Change the Surface area from Minimum to Maximum. You can imagine that a
solid reactant has been dissolved in a liquid.
How does this change how many Reactant B molecules are exposed to Reactant A?

gravity causes stares to cluster i think so

the answer is b. dilution

> 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.

the answer is option a.
