Question

Observe the following reaction \[ \text{a} \, \text{P}_4(s) + \text{b} \, \text{OH}^-(aq) + \text{H}_2\text{O}(l) \rightarrow \text{c} \, \text{PH}_3(g) + \text{d} \, \text{H}_2\text{PO}_4^-(aq) \] a, b, c and d are respectively

• A. 1, 3, 3, 1
• B. 1, 3, 2, 3
• C. 3, 1, 3, 1
• D. 1, 3, 1, 3

Hint:

For stoichiometry questions, ensure that the coefficients of the reactants and products are correctly matched in the reaction equation.

Answer 1

The Correct Option is A

In the reaction, the stoichiometric coefficients a, b, c, and d correspond to the balanced reaction as follows: a = 1, b = 3, c = 3, and d = 1. Hence, the correct matching is (1, 3, 3, 1).
