A. 2.0x1024 atoms of S to moles (3.3)
Fynjy0 [20]

3.3 moles of sulfur

Explanation:

To find the number of moles knowing the number of atoms we use Avogadro's number to formulate the following reasoning:

if in         1 mole of sulfur (S) there are 6.022 × 10²³ atoms of sulfur (S)

then in   X moles of sulfur (S) there are 2 × 10²⁴ atoms of sulfur (S)

X = (1 × 2 × 10²⁴) / (6.022 × 10²³)

X = 3.3 moles of sulfur

How does activation energy affect a chemical reaction ?
PilotLPTM [1.2K]

Enzymes affect the rate of the reaction in both the forward and reverse directions; the reaction proceeds faster because less energy is required for molecules to react when they collide. Thus, the rate constant (k) increases. Figure 3: Lowering the Activation Energy of a Reaction by a Catalyst.

hope this helps!
