Given:
rate = k [A]2
concentration is
0.10 moles/liter
rate is 2.7 × 10-5 M*s-1
Required:
Value of k
Solution:
rate = k [A]2
2.7 × 10-5 M*s-1
= k (0.10 moles/liter)^2
k = 2.7 x 10^-3
liter per mole per second
<span>A metal is one which ionizes easily and gives electrons whencompared to other elements.
So it should have a lower ionization energy.
Hence we would expect element 2 to be a metal.</span>
Answer:
1/2 ( the two answers given are not FRACTIONS)
Explanation:
Moles of CH3OH = 128 gm / 32 gm / mole = 4 moles
Moles of water 72 gm / 18 gm /mole = 4
Mole fraction of CH3OH = 4 / ( 4+4) = 4/8 = 1/2
