Answer:
BIOHEAT is a biodiesel mix that can be utilized (without equipment changes) in most home heaters. BIOHEAT promptly diminishes various hurtful discharges from heater use (up to 80% contingent upon blend used) and the oil is made from nearby feedstocks like utilized cooking oil
to solve the amount of sulfuric acid to maximize the profit
we need to establish the profit
let S(x) = 100x the selling price
P = S(x) – C(x)
P = 100x – ( 100,000 + 50x + 0.0025x^2)
P = 50x – 100000 – 0.0025x^2
Getting the first derivative and equating it to 0
0 = 50 – 0.005x
X = 10000 units of sulfuric acid
But the capacity is only 7000 units
<span>So 7000 units should be manufactured</span>
The half-life of the reaction is 101.9 min
<h3>First order reaction </h3>
When a reaction's pace and reactant concentration are inversely correlated, the process is known as a first-order reaction. To put it another way, the reaction rate doubles when the concentration does. One or two reactants can be present in a first-order reaction, as in the case of the decomposition process.
<h3>The half-life of first-order reaction:-</h3>
The amount of time it takes for the initial concentration of the reactant(s) to decrease by half is known as the half-life of a chemical reaction (abbreviated as "t1/2").
<h3 /><h3>Calculation:-</h3>
a→b
25% reacted means 75% remains
t=42 min
Rate constant
k=(2.303/t)(log a/a-x)
k=(2.303/42)(log 100/100-25 )
k=(0.054) (log 100/75)
k=(0.054)(0.1249)
k=0.0068 per min
half life
t1/2=(0.693/k)
=(0.693/0.0068)
=101.9 min
