Based on the effect of temperature on a reaction, a change in temperature affects the rate constant K.

Based on the Arrhenius equation, the y-intercept gives the value of ln A.

From the value of the slope, the value of Ea is 42.1 J/mol.

<h3>What is the effect of temperature on a reaction?</h3>

A change in the temperature of a reaction acts to increase the rate of reaction.

Change in temperature has no effect on the ideal gas constant.
Change in temperature has no effect on the activation energy.
Change in temperature has no effect on the concentration of reactants.
Change is temperature can either lower or increase the rate constant of a reaction.
Change in temperature has no effect on the order of reaction.

According to the Arrhenius equation, the y-intercept gives the value of ln A.

From the graph; slope = -Ea/R

Ea = -slope/R

Where;

Ea is activation energy
R is molar gas constant = 8.314 J/K.mol
Slope = -350 K

Ea = -(-350)/8.314

Ea = 42.1 J/mol

The painkiller, Advil® contains the active ingredient ibuprofen (IB), which has a pKb of

denis23 [38]

This problem is providing the basic dissociation constant of ibuprofen (IB) as 5.20, its pH as 8.20 and is requiring the equilibrium concentration of the aforementioned drug by giving the chemical equation at equilibrium it takes place. The obtained result turned out to be D) 4.0 × 10−7 M, according to the following work:

First of all, we set up an equilibrium expression for the given chemical equation at equilibrium, in which water is omitted for it is liquid and just aqueous species are allowed to be included:

$Kb=\frac{[IBH^+][OH^-]}{[IB]}$

Next, we calculate the concentration of hydroxide ions and the Kb due to the fact that both the pH and pKb were given:

$pOH=14-8.20=5.80$

$[OH^-]=10^{-5.8}=1.585x10^{-6}M$

$Kb=10^{-5.20}=6.31x10^{-6}$

Then, since the concentration of these ions equal that of the conjugated acid of the ibuprofen (IBH⁺), we can plug in these and the Kb to obtain:

$6.31x10^{-6}=\frac{(1.585x10^{-6})(1.585x10^{-6})}{[IB]}$

Finally, we solve for the equilibrium concentration of ibuprofen:

$[IB]=\frac{(1.585x10^{-6})(1.585x10^{-6})}{6.31x10^{-6}}=4.0x10^{-7}$
