On the incomplete reaction energy diagram below, draw a curve that shows the following two details. The relative activation energies of the two elementary steps

The enthalpy change of the overall reaction

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

they are all solids.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
