Which statements are true about reversible reactions?

Answer:

Option D is correct. Reversible reactions exhibit the same reaction rate for forward and reverse reactions at equilibrium.

Explanation:

Reversible reactions can be illustrated with the equation below:

A + B ⇄ C+ D

The reactants, A and B reacts to give the products, C and D. The products then react to give back the reactants.

Reversible reactions can reach equilibrium without a catalyst. Catalyst only speed up the rate at which the equilibrium is reached. This makes option A wrong.

In reversible reaction, both the forward and backward rate are equal. This makes option B wrong.

Option C is also wrong because no side (reactant of product) is favoured in a reversible reaction, unless the system is disturbed.

Option D is correct. Reversible reactions exhibit the same reaction rate for forward and reverse reactions at equilibrium.

option E is wrong.

Answer:

Reversible reactions exhibit the same reaction rate for forward and reverse reactions at equilibrium.

Reversible reactions exhibit constant concentrations of reactants and products at equilibrium

Explanation:

A reversible reaction is a reaction that can proceed in both forward and backward direction.

Equilibrium is attained in a chemical system when there is no observable change in the properties of the system.

At equilibrium, a reversible reaction is occurring in at same rate. That is, the forward and backward reaction is occurring at the same rate. As the rate of the forward and backward reaction remains the same, the concentrations of the reactants and products will also be the same in order for the equilibrium to be maintained.

1. It has been suggested that pain results from a change in the pH of solutions that surround nerves in the body.
Akimi4 [234]

Answer:

See Explanation

Explanation:

According to the question, it is established that the pain caused by a lot of insect bites owes to the acidity of the insect bites.

If this is true, then there is an urgent need to neutralize the acidic insect bite using a basic substance.

Hence the pH of the creams used to treat insect bites should be basic(having a high pH).

2. The compound methene can not exist because it is supposed to be derived from the alkane called methane which contains only one carbon atom.

In order to form an alkene, there must be a double bond between two carbon atoms. This is not possible because there is only one carbon atom in the hypothetical methene. Hence,  a compound named methene cannot exist.

Help plz:)))I’ll mark u Brainliest
Triss [41]

Answer:

Explanation:

We want the energy required for the transition:

CO  2 ( s ) + Δ → C O 2 ( g )

Explanation:

We assume that the temperature of the gas and the solid are EQUAL.

And thus we simply have to work out the product:

2 × 10^ 3 ⋅ g × 196.3 ⋅ J ⋅ g − 1  to get an answer in  Joules  as required.

What would be the energy change for the reverse transition:

C O 2 ( g ) + → C O 2 ( s ) ?
