Gas syringe bung
chips
25 cm of dilute
hydrochloric acid
Which channes slow down the rate of reaction?
Decrease the size of pieces of marble chips
Decrease surface area of marble chips
Inercase concentration of acid
Increase temperature of acid

Decrease surface area of marble chips.

Explanation:

Because the reaction goes on the surface  of marble chips, decreasing surface area of marble chips will decrease(slow down) the rate of the reaction.

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

> 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.
