Question

What is a RICE table?
(A) It is a way of keeping track of the data generated in the equilibrium reaction.
(B) It is a mathematical table showing relationships among reactants.
(C) It is a table that holds data from a chemical reaction.
(D) It is a way of keeping track of concentration of reactions.
(E) It is a mathematical table showing relationships among products.

Answer 1

Hint: RICE table is also known as ICE table or ICE boxes or RICE boxes or ICE charts and RICE charts. R in the RICE table stands for reaction, I in the RICE table stands for initial concentration, C in the RICE table stands for change in concentration and E in the RICE table stands for equilibrium concentration.

Complete step by step solution:
Reaction (R): a process which involves the rearrangement of the molecular or the ionic structure of a substance or a change in physical form is known as a reaction.
Initial concentration (I): the first measured concentration or the concentration at the beginning of a chemical reaction is known as initial concentration.
Change in concentration (C): the change in concentration means the change in concentration of reactant or product per unit time.
Equilibrium concentration (E): the concentration of the reactants and products during equilibrium is known as the equilibrium concentration.
RICE table is the way to organize the data about the equilibrium system in order to solve the question easily.
For a general reaction: $aA\rightleftharpoons bB+cC$
RICE table will be written as:

Reaction	$aA\rightleftharpoons bB+cC$
Initial concentration	$[{{A}_{(i)}}]\text{ }\!\![\!\!\text{ }{{\text{B}}_{(i)}}\text{ }\!\!]\!\!\text{ }\!\![\!\!\text{ }{{\text{C}}_{(i)}}\text{ }\!\!]\!\!\text{ }$
Change in concentration	$ax\text{ bx cx}$
Equilibrium concentration	$[{{A}_{(e)}}]\text{ }\!\![\!\!\text{ }{{\text{B}}_{(e)}}\text{ }\!\!]\!\!\text{ }\!\![\!\!\text{ }{{\text{C}}_{(e)}}\text{ }\!\!]\!\!\text{ }$

Hence the correct answer is option (D).

Note: The RICE table also help to calculate the equilibrium constant or the same reaction occurring as a mixture of gases. The equilibrium constant is defined as the ratio of the product of the concentration of product to the product of the concentration of reactant each raised to the power of their respective stoichiometric coefficient.
