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.

First, calculate the amount fo Na2O that should be produced with the given amount of sodium using proper dimensional analysis and the balanced chemical reaction,
theoretical amount of Na2O = (54.1 g of Na)(1 mol Na/23 g Na)(2 mos Na2O/4 mols Na)(62 g Na2O/ 1mol Na2O)
theoretical amount of Na2O = 72.9 g of Na2O
Calculation of percent yield,
% yield = (61.8 g Na2O) / (72.9 g of Na2O) x 100%
% yield = 84.75%
Answer: 84.75%
Some examples of endothermic reactions include melting solid salts, cooking an egg, baking bread, water evaporations and melting ice cubes
