Vanyuwa [196]
For all question, all you need to use is the mole-mole ratio. 

a) 25 moles C2H6O (3 moles O2/ 1 mol C2H6O)= 75 moles O2 

b) 30 moles O2 (1 moles C2H6O/ 3 moles O2)= 10 moles C2H6O

c) 23 moles CO2 (3 moles O2/ 2 moles CO2) = 34.5 moles O2

d)  41 moles H2O ( 1 moles C2H6O/ 3 moles H2O= 13.7 moles C2H6O

The rate of a chemical reaction is related to:_______
aalyn [17]

The correct answer for this question is activation energy, orientation, and frequency.

The rate of a chemical reaction is directly related to its activation energy because the higher the activation energy the lower is the rate of reaction as we know the reaction only proceed when the reactants have absorbed the enough heat energy to reach the transition state. Thus activation energy determines the rate of reaction.

The orientation of the particles is also very important as we know that the reaction between the two reactants only occur when they collide with proper orientation in time the greater the probability of the collision the greater is the rate of reaction and also the number of collisions also determines the rate of reaction.

The frequency is directly proportional to the rate of chemical reaction as the frequency of the collision increases the rate of the chemical reaction also increases.
