What does lower case k stand for?
DaniilM [7]
Just for more clarification, lowercase k is the rate constant. Uppercase K is the equilibrium constant. You can actually use k to find K (equilibrium constant). K=k/k' This means that the equilibrium constant is the rate constant of the forward reaction divided by the rate constant of the reverse reaction

Choose the statement that best describes the effects of a higher or lower pH on enzymes.
matrenka [14]
<h3>Answer:</h3>

Higher or lower pH affect the structure of the enzyme and reduces the enzyme activity.

<h3>Explanation:</h3>
  • Enzymes are biological molecules that speed up the rate of chemical reactions.
  • Enzyme activity is affected by several factors which include temperature, pH, and enzyme inhibitors.
  • Enzymes work on specific molecules known as substrates. They are substrate-specific.
  • Enzymes work best at optimum pH and temperature.
  • Higher or lower pH affects the structure and charges of an enzyme thus affecting enzyme activity.
  • Lower temperature deactivates the enzymes while higher temperatures denature the enzymes.

According to the following reaction, how many moles of iron(III) chloride will be formed upon the complete reaction of 26.2 gram
Andre45 [30]

Answer:

0.469 mol FeCl₃

Explanation:

Your reaction as a chemical equation is:

2 Fe (s)  +  3 Cl₂ (g)  ⇒  2 FeCl₃ (s)

You have 26.2 grams of iron.  Convert to moles of iron.

(26.2 g)/(55.845 g/mol) = 0.4692 mol

Use the mole ratio from the chemical equation to convert moles of iron to moles of iron(III) chloride.

(0.4692 mol Fe) × (2 mol FeCl₃/2 mol Fe) = 0.469 mol FeCl₃

You will have 0.469 moles of iron(III) chloride at the end of the reaction.
