How do we know that matter is composed of atom?
Nataly [62]

Answer:

The number of protons in the nucleus determines which element an atom is, while the number of electrons surrounding the nucleus determines which kind of reactions the atom will undergo. The three types of subatomic particles are illustrated below for an atom of helium—which, by definition, contains two protons.

N which direction will the net reaction proceed.
finlep [7]

Answer:

1) The correct answer is option b.

2) The correct answer is option a.

Explanation:

1)

X+Y\rightleftharpoons Z

At 300 K, the value of the K_p=1.00

The K_c and K_p is related by :

K_p=K_c\times (RT)^{\Delta n}

where,

K_p = equilibrium constant at constant pressure

K_c = equilibrium concentration constant

R = gas constant = 0.0821 L⋅atm/(K⋅mol)

T = temperature = 300 K

\Delta n = change in the number of moles of gas = 1 - 2 = -1

Now put all the given values in the above relation, we get:

1.00=K_c\times (0.0821 L atm/(K mol)\times 300)^{-1}

K_c=24.63

The K_c of the reaction = 24.63

Given = [X] = [Y] = [Z] = 1.0 M

Value of reaction quotient = Q

Q=\frac{[Z]}{[X][Y]}=\frac{1.0 M}{1.0M\times 1.0 M}=1

Q, the equilibrium will move in forward direction that is in the right direction.

2)

X+Y\rightleftharpoons Z

At 300 K, the value of the K_p=1.00

Given = P_x = P_z = 1.0 atm, P_y = 0.50 atm

Value of reaction quotient in terms of partial pressure = Q_p

Q_p=\frac{P_z}{P_x\times P_y}=\frac{1.0 atm}{1.0 atm\times 0.50 atm}

Q_p=2

Q_p>K_pthe equilibrium will move in backword direction that is in the left direction.
