Answer:
by providing an alternative pathway with a lower activation energy
Explanation:
Cataysts are the substances that neither consumed nor produced during a chemical reaction, but increase the rate of the reaction.
So, catalysts remain chemically unchnaged after the completion of the reaction.
For a reaction to occur, reactants molecule must collide and successful collisions lead to product formation.
A certain minimum amount of energy is required for successful collision. This minimum amounr of energy is called activation energy.
One way to increase speed of reaction is to provide energy to the reactants and other way to increase speed is to provide alternate pathway with lower activation energy.
Catalyst increases a rate of reaction by providing an alternate pathway with lower activation energy.
Therefore, the correct option is option b 'by providing an alternative pathway with a lower activation energy'
Answer: 39.948
Explanation:
How many grams Argon in 1 mol? The answer is 39.948. We assume you are converting between grams Argon and mole. You can view more details on each measurement unit: molecular weight of Argon or mol The molecular formula for Argon is Ar.

Answer:
Empirical formula = S₁Cl₂ = SCl₂
Explanation:
The empirical formula of a compound is the simplest whole number ratio of each type of atom in a compound.
This compound contains 31.1% sulfur and 68.9% chlorine.
That is 100g of the compound contains 31.1 g of sulfur and 68.9 g of chlorine.
Convert the mass of each element to moles using the molar mass from the periodic table.
Moles of Sulfur = 
= 0.9699
Moles of Chlorine= 
= 1.9434
Divide each mole value by the smallest number of moles calculated.
Units of sulfur = 
= 1
Units of Chlorine = 
= 2
Empirical formula = S₁Cl₂ = SCl₂
