What is the measure of force per unit area.
Brut [27]

Pressure

Explanation:

Pressure is a measure of force per unit area.

Pressure is defined as the force exerted on a body across a unit area. The unit of pressure is N/m² or Pascal.

                Pressure = \frac{Force}{Area}

The more the force acting on a body the more the pressure felt. A small surface area and a large force increases pressure on a body.

it is right to say that pressure is proportional to force but inversely proportional to area.

In the activity, click on the E∘cell and Keq quantities to observe how they are related. Use this relation to calculate Keq for
inessss [21]

Answer:

The standard cell potential of the reaction is 0.78 Volts.

Explanation:

Cu^{2+}(aq)+Fe(s)\rightarrow Cu(s)+Fe^{2+}(aq)

Reduction at cathode :

Cu^+(aq)+2e^-\rightarrow Cu(s)

Reduction potential of  Cu^{2+} to Cu=E^o_{1}=0.34 V

Oxidation at anode:

Fe(s)\rightarrow Fe^{2+}(aq)+2e^-

Reduction potential of  Fe^{2+} to Fe=E^o_{2}=-0.44 V

To calculate the E^o_{cell} of the reaction, we use the equation:

E^o_{cell}=E^o_{red,cathode}-E^o_{red,anode}

Putting values in above equation, we get:

E^o_{cell}=0.34V -(-0.44 V)=0.78 V

The standard cell potential of the reaction is 0.78 Volts.
