Free_Kalibri [48]4 years ago
5 0

Answer:

  • Option d. i<u><em>t is higher than the energy of both reactants and products</em></u>

Explanation:

<em>Activated complex</em>, also known as transition state, is the intermediate structure formed in the course of a chemical reaction.

The activated complex is very unstable and of short life: it is at the peak of the potential chemical diagram, and can transform either into the reactants (backward) or the products (forward).

The activation energy of the reaction is the energy needed to reach the activated complex, then both reactants and products are lower in potential chemical energy than the activated complex, which is what explains why the activated complex can transform into one or another, reactants or products.

Ira Lisetskai [31]

Answer:

2.11\ * 10^{-2}  is the correct answer to the given question.

Explanation:

Given k=6.40 x 10-3 min-1.

According to the first order reaction .

The concentration of time can be written as

[\ A\ ]\ = \ [\  A_{0}\ ]  * e \ ^\  {-kt}

Here [\ A\ ]_{0} = Initial concentration.

So  [\ A\ ]_{0}= 0.0314 M

Putting this value into the above equation.

0.0314 \ *\ e^{6.40 x 10^{-3} \ *  \ 62.0  }

=0.211 M

This can be written as

=\ 2.11 *\ 10^{-2}

A 25 liter gas cylinder contains 10 mole of carbon dioxide. Calculate the pressure, in atm, of the gas at 325K.
Arada [10]

<u>Answer:</u> The pressure of carbon dioxide gas is 11 atm

<u>Explanation:</u>

To calculate the pressure of gas, we use the equation given by ideal gas equation:

PV = nRT

where,

P = pressure of the gas = ?

V = Volume of gas = 25 L

n = number of moles of gas = 10 mole

R = Gas constant = 0.0821\text{ L atm }mol^{-1}K^{-1}

T = temperature of the gas = 325 K

Putting values in above equation, we get:

P\times 25L=10mol\times 0.0821\text{ L atm }mol^{-1}K^{-1}\times 325K\\\\P=11atm

Hence, the pressure of carbon dioxide gas is 11 atm
