Lowering the activation energy
Answer: The density of glycerine is
Explanation: We are given density of glycerine in which is
To convert t into , we are given conversion rates:
454 grams = 1 pound
So, 1 gram will be equal to
Similarly,
So, will be equal to
Converting the density of glycerin from to using above conversion rates, we get:
Density of glycerin is

Answer:
a) kc= [SO3 ]/([SO2 ][O2 ])
b) kc= 2.27*10⁶ M⁻¹
v) the reaction is product-favored
Explanation:
for the reaction, the equilibrium constant is
SO2 (g) + O2 (g) <-----> SO3 (g)
he equilibrum constant is
kc= [SO3 ]/([SO2 ]*[O2 ])
replacing values
kc= [SO3 ]/([SO2 ]*[O2 ]) = 1.01*10⁻² M/(3.61*10⁻³M*6.11 x 10⁻⁴ M) = 2.27*10⁶ M⁻¹
since kc>>1 the reaction is product-favored
The student is worng, because CO₂ is acidic oxide. When an acidic oxide reacts with water, acid is formed. In the student's case, the following reaction happens:
H₂O + CO₂ ⇒ H₂CO₃
The H₂CO₃ is carbonic acid and it is the scoure of the H⁺ atoms. The sample is not contaminated.
