Answer: The dotted line shows a new potential energy diagram with a shorter activation energy hill than that in the original potential energy diagram.
Explanation:
Activation energy is the extra amount of energy required by the reactants to cross the energy barrier to get converted into products.
When a catalyst is added, it lowers down the activation energy which is shown by a dotted line. As now less energy is required, more of reactants can cross the energy barrier and get converted to products and thus increase the rate of reaction.
A catalyst increases the rate of reaction for both exothermic and endothermic reactions.
Answer:
The right answer is "60.56 atm".
Explanation:
As we know,
Vander wall's equation is:
⇒
or,
⇒
Here,
a = 3.59 L² atm mol⁻²
b = 0.0427 L mol⁻¹
By putting the values in the above equation, we get
⇒
