Th answer is C.
A catalyst is an organic or inorganic substancec which will increase the rate of chemical reaction. It will not be used up in the chemical reaction.
Which statement does not describe a catalyst? A) A catalyst may be an inorganic substance. B)...

Which statement below is true only for a homogeneous catalysts? a. A homogeneous catalyst increase the rate of reaction by providing an alternative pathway with a lower activation energy. b. A homogeneous catalyst is a solid substance to which liquid or gaseous reactants will adhere to the surface of the catalyst. c. A homogeneous catalyst is when the catalyst is in the same physical state as the reactant. d. A homogeneous catalyst will eventually be consumed in a chemical reaction.

2. BigMoney Inc. has also had a major spill of inorganic Fe that contaminated the soil around their plant. Scientists at BigMoney have developed mechanisms for removing Fe from soil, but have not found one for Fe. They want to know, on a strictly theoretical basis (regardless of whether bacteria exist im nature that actually.do these specific reactions) f there are any types of bacteria a. Is this an oxidation or reduction? (0.5 point) b. Is Fe acting as an...
How does a positive catalyst generally affect a chemical reaction? A catalyst increases the temperature of the reaction which speeds the reaction rate. A catalyst reduces the frequency factor which speeds the reaction rate. A catalyst reduces the amount of solvent required which slows the reaction rate. A catalyst reduces activation energy which speeds the reaction rate.
