Reika [66]

Answer:

A: catalyst

Explanation:

In Chemistry, the rate of reaction of chemical elements (reactants) can be sped to produce a chemical compound or elements (products), through the addition of a catalyst that is unaffected by the reaction.

This ultimately implies that, to speed up a chemical reaction, add a catalyst that is unaffected by a reaction.

For example, an enzyme refers to a biological catalyst that is typically used to speed up (accelerate) the rate of a chemical reaction by lowering the activation energy of its reactants.

An enzyme can be defined as a biological catalyst that typically lowers the activation energy of a biological reaction. When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.

Generally, an increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.

Calculate the enthalpy of reaction for 2CO + O2 → 2CO2. given the following bond energies:
kotegsom [21]

Answer : The enthalpy change for the reaction is 1043 kJ/mol.

Explanation :

The given chemical reaction is:

2CO+O_2\rightarrow 2CO_2

As we know that:

The enthalpy change of reaction = E(bonds broken) - E(bonds formed)

\Delta H=[(2\times B.E_{C\equiv O})+(1\times B.E_{O\equiv O})]-[2\times B.E_{C=O}]

Given:

B.E_{C\equiv O} = 1074 kJ/mol

B.E_{O\equiv O} = 499 kJ/mol

B.E_{C=O} = 802 kJ/mol

Now put all the given values in the above expression, we get:

\Delta H=[(2\times 1074kJ/mol)+(1\times 499kJ/mol)]-[2\times 802kJ/mol]

\Delta H=1043kJ/mol

Therefore, the enthalpy change for the reaction is 1043 kJ/mol.
