Answer: The balance of the reaction shifts toward the endothermic reaction.

Explanation:

An ENDOTHERMIC REACTION requires input of HEAT ENERGY to drive it FORWARD from reactants, unto completion of products.

So, on increasing the temperature (available heat) the REVERSIBLE REACTION favors the shifts towards the endothermic reaction

Molecular iodine, I2 (g), dissociates into iodine atoms at 545K with a first order rate constant of 0.344 1/s. If you start with
Dennis_Churaev [7]

Answer:

0.00915 M of I_2 remain after 5.16 seconds.

Explanation:

Using integrated rate law for first order kinetics as:

[A_t]=[A_0]e^{-kt}

Where,  

[A_t] is the concentration at time t

[A_0] is the initial concentration

Given that:

The rate constant, k = 0.344 s⁻¹

Initial concentration [A_0] = 0.054 M

Final concentration [A_t] = ? M

Time = 5.16 s

Applying in the above equation, we get that:-

[A_t]=0.054e^{-0.344\times 5.16}\ M=\frac{1\times \:0.054}{e^{1.77504}}\ M=0.00915\ M

<u>0.00915 M of I_2 remain after 5.16 seconds.</u>

Convert 99 moles of CO2 to atoms
lorasvet [3.4K]

Answer:

              1.78 × 10²⁶ Atoms

Explanation:

Relation between number of molecules and moles is,

No. of Molecules = Moles × 6.022 × 10²³ Molecules/mol

No. of Molecules = 99 mol × 6.022 × 10²³ Molecules/mol

No. of Molecules = 5.96 × 10²⁵ Molecules

Also, In CO₂ Molecule there are 3 atoms.

So,

No. of atoms = 5.96 × 10²⁵ Molecules × 3

No. of atoms = 1.78 × 10²⁶ Atoms
