H2F2(g) → H2(g) + F2(g)
ΔU = -59.6 kJ mol-1 at \(27 \degree\) C
ΔH = ΔU +ΔngRT
=-59.6+ \(\frac{1 \times 8.314 \times 300 }{ 1000}\)
\(= -57.10 kJ mol^-1\)
Let A be a 3 × 3 matrix such that \(\text{det}(A) = 5\). If \(\text{det}(3 \, \text{adj}(2A)) = 2^{\alpha \cdot 3^{\beta} \cdot 5^{\gamma}}\), then \( (\alpha + \beta + \gamma) \) is equal to:
SN1 reaction mechanism takes place by following three steps –
The SN2 reaction mechanism involves the nucleophilic substitution reaction of the leaving group (which generally consists of halide groups or other electron-withdrawing groups) with a nucleophile in a given organic compound.
The mechanism of an electrophilic aromatic substitution reaction contains three main components which are:
The electrophilic substitution reaction mechanism is composed of three steps, which will be discussed more below.
