Calculate the time it takes for a reactant to reach 1% of its initial
mole content in a constant volume batch reactor if ra = -kca, k = 0.23 min-1.
plot the concentration profile, ca(t).
b) what assumptions were made in the application of the general mole balance equation for
the case of (a) the batch reactor, (b) cstr and (c) pfr?

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
