Answer:
A catalyst increases the rate of reaction by decreasing activation energy. ... Enzymes are highly substrate specific and catalyze reactions by providing an alternate pathway of lower activation energy.

Answer:
18.095 %.
Explanation:Theoretical yield is the yield calculated from the balanced chemical equation. In this reaction theoretical yield is 21g. Actual yield = 3.8g. Hence, the percent yield for this reaction is 18.095 %.
Given -
T = 450K
∆H = 3000J
∆S = 4J/K
Using formula
∆G = ∆H - T∆S
∆G = 3000- 4*450
∆G = 1200 Joule
∆G is positive so the reaction is non spontaneous!
