A chemical reaction can be reversed if?

1 answer:

8 0

A chemical reaction can be reversed if the energy of the products exceeds the activation energy threshold.

<h3>What are reversible reactions?</h3>

Reversible reactions are reactions which can proceed in two directions.

In reversible reactions, reactants can form products and products can also break down to form reactants.

For a chemical reaction to be reversed, the original reaction conditions leading to formation of products are reversed.

Therefore, a chemical reaction can be reversed if the energy of the products exceeds the activation energy threshold.

Exercise A mixture of 250 mL of methane, CH4, at 35 °C and 0.55 atm and 750 mL of propane, C3Hg, at 35° C and 1.5 atm, were intr

dalvyx [7]

Explanation:

The given data is as follows.

$V_{1}$ = 250 mL, $V_{2}$ = 750 mL

$T_{1}$ = $35^{o}C$ = 35 + 273 K = 308 K

$T_{2}$ = 35 + 273 K = 308 K

$P_{1}$ = 0.55 atm, $P_{2}$ = 1.5 atm

P = ? , V = 10.0 L

Since, temperature is constant.

So, $P_{1}V_{1} + P_{2}V_{2}$ = PV

Now, putting the given values into the above formula as follows.

$P_{1}V_{1} + P_{2}V_{2}$ = PV

$0.55 atm \times 250 mL + 1.5 atm \times 1.5 atm$ = $P \times 10.0 L$

P = 0.126 atm

As, 1 atm = 760 torr. So, $0.126 atm \times \frac{760 torr}{1 atm}$ = 95.76 torr.

Thus, we can conclude that the final pressure, in torr, of the mixture is 95.76 torr.
