What is the overall rate order of the following reaction a + 2b → c + d ? a zero
b first
c second
d third

I think zero is the answer^_^

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope 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.
