The following term refers to the relative proportion of chemical components?
a) Togetherness
b) Stoichiometry
c) Metric
d) Colligative
b) Stoichiometry
Which of the following is true about catalysts?
a) A catalyst increases the rate of the desired reaction by increasing the activation energy for that reaction.
b) A catalyst can change the thermodynamics of a reaction, thus making the desired reaction more favorable in terms of the change in Gibbs Free Energy.
c) A catalyst changes the mechanism of the desired reaction, resulting in a decrease in the activation energy of the reaction and an increase in the reaction rate.
d) Most reactions require one mole of catalyst to produce one mole of the desired product.
c) A catalyst changes the mechanism of the desired reaction, resulting in a decrease in the activation energy of the reaction and an increase in the reaction rate.
