Answer:
When you lower the temperature, the molecules are slower and collide less. That temperature drop lowers the rate of the reaction. When you increase the pressure, the molecules have less space in which they can move. That greater density of molecules increases the number of collisions.

Answer:
B. Kinetic energy
Explanation:
moving is kinetic, potential is inside a body
No. of moles = mass / molecular weight
n = m / Mr
n = 3 g / 23 g/mol
n = 0.13 mol / 4
n = 0.0326 mol
Mr of Na2O = 23+23+16 = 62 g/mol
n = 0.0326 mol x 2 (because you have 2x Na2O) = 0.0652 mol
m = n x Mr
m = 0.0652 mol x 62 g/mol
m = 4.04 g
