The rate law for a reaction that is first order in both reactants is Rate=k[A][B]. Therefore to find the rate you plug in the values you are given to get the equation rate=0.5×0.0183×0.0168 to get Rate=1.54×10⁻⁴ mol/Ls.
I hope this helps. Let me know in the comments if anything is unclear.

is the partial pressure of water with a value 753 mm of Hg
Now substituting values
Answer: Thus, they ensure that the cells receive nutrients and can eliminate waste, thereby enabling them to survive and function properly.
Explanation: yes.
Answer:
pH of the buffer solution is 1.76
Explanation:
To find the pH of a buffer we can use Henderson-Hasselbalch equation:
pH = pKa + log [A⁻] / [HA]
<em>Where pKa is -log Ka= 1.77 And [A⁻] is molar concentration of conjugate base, NaHSO₃ and [HA] molar concentration of weak acid, H₂SO₃</em>
<em />
Replacing values of the problem:
pH = 1.77 + log [0.304M] / [0.310M]
pH = 1.76
<h3>pH of the buffer solution is 1.76</h3>
