100%
A second-order chemical reaction involves the interaction of onc molccule of a substance P
with one molecule of another substance Q to produce one molecule of another substance X. Suppose
that p and q are the initial concentrations of P and Q and let r(t) be the concentration of X at time
t. Then p- I(t) and q -r(t) are the concentrations of P and Q at time t, and the rate at which the
reaction occurs is given by the equation
dr
*(I - b)(I – d)o=
dt
where a is a positive constant. Solve the initial value problem with r(0) = 0 assuming p # q.
Answ: r(t) = Pq(e®(q-p)t _1
qea(q-p)t-p
, you may nced to manipulate your answer to get this.
