False, you'd have less pressure if you increased the area.
P=F/A, you're dividing by A. If you say, doubled A, you'd have only half the pressure.
The complete question is as follows: At 700 K, decomposes to carbon and chlorine. The Kp for the decomposition is 0.76.
Find the starting pressure of at this temperature that will produce a total pressure of 1.1 atm at equilibrium.
Answer: The starting pressure of is 0.79 atm.
Explanation:
The equation for decomposition of is as follows.
Let us assume that initial concentration of is 'a'. Hence, the initial and equilibrium concentrations will be as follows.
Initial: a 0 0
Equilibrium: (a - x) 0 2x
Total pressure = (a - x) + 2x = a + x
As it is given that the total pressure is 1.1 atm.
So, a + x = 1.1
a = 1.1 - x
Now, expression for equilibrium constant for this equation is as follows.
Hence, the value of 'a' is calculated as follows.
a + x = 1.1 atm
a = 1.1 atm - x
= 1.1 atm - 0.31 atm
= 0.79 atm
Thus, we can conclude that starting pressure of is 0.79 atm.

Answer:
44 years
Explanation:
Use half life equation:
A = A₀ (½)^(t / T)
where A is the final amount,
A₀ is the initial amount,
t is time,
and T is the half life.
0.25 A₀ = A₀ (½)^(t / 22)
0.25 = (½)^(t / 22)
t / 22 = 2
t = 44
Answer: 79 J
Explanation:
The value of the kinetic energy at the bottom would be equal to the value of potential energy at the top. This comes from the conservation of energy. At the top, the bob of mass just has potential energy due to its position. At the bottom, potential energy converts entirely to kinetic energy due to its motion.
It is given that mass of the bob is, m = 0.18 kg
height from which it is dropped is, h = 45 m
acceleration due to gravity, g = 9.8 m/s²
Thus, K.E. = P.E. = m g h = 0.18 kg× 45 m × 9.8 m/s² = 79 J
