How does a catalyst work? Select the correct answer from the options below.

Use the collision theory to explain how increasing the surface area of a solid reactant increases the rate of reaction.

A. $50 {\mathrm{cm}}^3$ of $0.5 \mathrm{mol} {\mathrm{dm}}^3$

B. $10 {\mathrm{cm}}^3$ of $1.0 \mathrm{mol} {\mathrm{dm}}^3$

C. $25 {\mathrm{cm}}^3$of $0.5 \mathrm{mol} {\mathrm{dm}}^3$

A. $50 {\mathrm{cm}}^3$ of $0.5 \mathrm{mol} {\mathrm{dm}}^3$

B. $10 {\mathrm{cm}}^3$ of $1.0 \mathrm{mol} {\mathrm{dm}}^3$

C. $25 {\mathrm{cm}}^3$of $0.5 \mathrm{mol} {\mathrm{dm}}^3$

Why would B have the fastest initial rate of the reaction?

Which one of these explanations about the effect of increasing the concentration of the reactants on the rate of reaction is completely correct?

What is boltzmann distribution?

Explain why a $10 °\mathrm{C}$ rise in temperature can approximately double the rate of a reaction.

Which one of these statements about the Boltzmann curve is correct?

Explain whether the reaction below is an example of heterogeneous catalysis or homogeneous catalysis:

$2{\mathrm{SO}}_2\left(\mathrm{g}\right) + {\mathrm{O}}_2\left(\mathrm{g}\right) \stackrel{{\mathrm{V}}_2{\mathrm{O}}_5\left(\mathrm{s}\right)}{\rightleftharpoons } {\mathrm{SO}}_3\left(\mathrm{g}\right)$
