Question

For a reaction pA + qB $\to$ Products, the rate law expression is r = k[A]$[B{]}^m$, Then:

• A. (p + q) $=$ (1 + m)
• B. (p + q) $>$ (1 + m)
• C. (p + q) may or may not be equal to (1 + m)
• D. (p + q) $\ne$ (1 + m)

Answer 1

The correct option is C (p + q) may or may not be equal to (1 + m)

(p + q) may or may not be equal to (1 + m).

p and q are the stoichiometric coefficients in the balanced chemical equation and l and m are the orders of reaction with respect to A and B respectively. p and q can differ from l and m.
