According to this formula:
K= A*(e^(-Ea/RT) when we have K =1.35X10^2 & T= 25+273= 298K &R=0.0821
Ea= 85.6 KJ/mol So by subsitution we can get A:
1.35x10^2 = A*(e^(-85.6/0.0821*298))
1.35x10^2 = A * 0.03
A= 4333
by substitution with the new value of T(75+273) = 348K & A to get the new K
∴K= 4333*(e^(-85.6/0.0821*348)
= 2.16 x10^2
Potential energy is stored energy. Kinetic energy involves movement.
If a ball is on the top of a hill, it has the most potential energy on the very top of the hill. The kinetic energy is also 0 at this point.
If the ball rolls down the hill, potential energy decreases while kinetic increases.

1.turn the revolving turret so that low power lens come into position
2 place the microscope slide on the stage
3 look at the objective lens and the stage from the side as you turn adjust knob so that stage can move upward
4 look through the eyepiece and move the focus knob until image come into focus
5.adjust the condenser to regulate thee amount of light
6 move the microscope slide around until the sample is in the center of field of view
