Explanation:just did the question and I guessed an answer cuz I didnt know it and I got it wrong so its a for a p e x
Answer:
0.17325 moles per liter per second
Explanation:
For a first order reaction;
in[A] = in[A]o - kt
Where;
[A]= concentration at time t
[A]o = initial concentration
k= rate constant
t= time taken
ln0.5 =ln1 - 2k
2k = ln1 - ln0.5
k= ln1 - ln0.5/2
k= 0 -(0.693)/2
k= 0.693/2
k= 0.3465 s-1
Rate of reaction = k[A]
Rate = 0.3465 s-1 × 0.50 mol/L
Rate = 0.17325 moles per liter per second
The strumming is mechanical energy
the notes heard is sound energy
so use D
Acid of x bottle is highly reactive because solute is more and acid of y bottle is less reactive because solvent is more.
