Be sure to answer all parts. Acetone is one of the most important solvents in organic chemistry. It is used to dissolve everythi

ng from fats and waxes to airplane glue and nail polish. At high temperatures, it decomposes in a first-order process to methane and ethene (CH2═C═O). At 600°C, the rate constant is 8.7 × 10−3 s−1. (a) What is the half-life of the reaction

Answer:

Half life = 79.67 sec

Explanation:

Given that:

k = 8.7\times 10^{-3}\ s^{-1}

The expression for half life is shown below as:-

t_{1/2}=\frac{\ln2}{k}

Where, k is rate constant

So,  

t_{1/2}=\frac{\ln2}{8.7\times 10^{-3}\ s^{-1}}

t_{1/2}=114.94252\ln \left(2\right)\ sec=79.67\ sec

Half life = 79.67 sec

If a buffer solution is 0.130 M in a weak acid (K_a = 1.7 x 10^-5) and 0.590 M in its conjugate base, what is the pH?
Serggg [28]
Use the Henderson-Hasselbach equation:
pH = pKa + log[base]/[acid]
pH = -log(1.7 x 10^-5) + log(0.590/0.130) = 5.43
