Answer: The rate of backward reaction increases.
Explanation: I'm sorry!
Answer: 1. 199.995 g of NaOH & 2. 2.014 g of H2
Explanation:
1. 5.00 mol H2O x __2 mol NaOH__ x __39.999 g__
2 mol H2O 1 mol
= 199.995 g of NaOH
2. 36 g H2O x __1 mol __ x __1 mol H2__ x __2.016 g__
18.016 g 2 mol H2O 1 mol H2
= 2.014 g of H2
Answer:
T₂ = 687.6 K
Explanation:
Given data:
Initial pressure = 108 Kpa
Initial temperature = 20°C
Final temperature = ?
Final pressure = 2.50 atm
Solution:
Initial pressure = 108 Kpa = 108/101 = 1.06588 atm
Initial temperature = 20°C = 20+273.15 = 293.15 k
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
1.06588 atm / 293.15 K = 2.5 atm/T₂
T₂ = 2.5 atm ×293.15 K / 1.06588 atm
T₂ = 732.875 atm. K /1.06588 atm
T₂ = 687.6 K
Answer:
The concentration of reactants have no effect on the rate of reaction.
Explanation:
The strength of the nucleophile doesn't affect the reaction rate of an SN1 since the nuleophile is not involved in the rate determining step. Increasing the concentration of the substrate (which is a reactant) increases the rate of reaction even though increasing the concentration of the nucleopohile has no effect on the rate of reaction. The use of polar protic solvents assist an SN1 reaction hence the solvent used can affect the rate of reaction. However, temperature affects an SN1 reaction. Increasing the temperature will increase the rate of E1 elimination reaction rather than the SN1 reaction since the both are competing reactions. Lowering the temperature favours SN1 reaction. Hence the answer.
Since, Mendeleev noticed that Tellurium has chemical properties like the other elements included in the same group; he did not know that neutrons can affect atomic mass. Therefore, Mendeleev's Tellurium and Iodine aberration happened because the Tellurium that he got has a prevalence of a heavier Tellurium isotope making it a greater weight than Iodine.
