Consider the hypothetical equation $aA + bB \rightarrow cC+Dd$: Which of the following represents correct rate equation?
Correct Answer:B
Explanation:
For a general reaction, rate = k[A]$^x$[B]$^y$ where x and y are experimentally determined.
88
If a reaction rate does not change with concentration then it is
Correct Answer:D
Explanation:
Zero-order reactions have rates independent of concentration.
89
Which of the following is CORRECT Arrhenius equation?
Correct Answer:B
Explanation:
Arrhenius equation is k = Ae$^{-E_a/RT}$.

In endothermic reaction, the heat content of the
Correct Answer:C
Explanation:
Endothermic reactions absorb heat, so products have higher heat content.
91
In endothermic reaction, the heat content of the
Correct Answer:C
Explanation:
In an endothermic reaction, the products have higher heat content than the reactants because energy is absorbed from the surroundings.
