For the elementary reaction `2A + B to 3C`, if the rate of appearance of C at time 't' is `1.3 xx 10^(-4)mol L^(-1)s^(-1)`, calculate at this time (i) rate of the reaction (ii) rate of disappearance of A.

Explanation

To solve the problem, we need to find the rate of the reaction and the rate of disappearance of reactant A for the given elementary reaction:

**Reaction:**
\[ 2A + B \rightarrow 3C \]

Given:
Rate of appearance of C, \(\frac{dC}{dt} = 1.3 \times 10^{-4} \, \text{mol L}^{-1} \text{s}^{-1}\)
