XII. KINETIC RATE EQUATIONS

Read the equation

This relation defines B* ≈ 36.2 bonds at 300K in the source section “XII. KINETIC RATE EQUATIONS”. It specifies the displayed relationship between the named quantities or parameters. Its interpretation depends on the source’s stated variables and conditions; this record does not assign an unprovided physical or cognitive meaning to them.

Terms & definitions

The recovered passage does not supply a separate symbol table. Read the source context for the notation used in this version; familiar letters may carry different meanings in other builds.

How it works

1. Read the displayed expression together with the surrounding source statement; it is retained as an expression rather than silently completed into an equality.

2. Substitute the source-defined variables or recorded values and follow the displayed arithmetic and indexing exactly.

3. Use this version’s variable definitions and update order. The same symbol may be assigned a different meaning in another build.

Assumptions & limits

• This source expression was recovered from the pinned code revision. Its presence does not establish that the associated program was built, run, or scientifically validated.

Original context

        double sum = 0.0;
        for (int n = 1; n <= TOTAL_BONDS; ++n) {
            sum += rates_.equilibrium_occupation(n, 0.0);
        }
        return sum;
    }

    // B* ≈ 36.2 bonds at 300K
    // θ* = B*/44 ≈ 0.82
    double steady_state_occupation() const {
        return steady_state_bonds() / TOTAL_BONDS;
    }

    // Get current bond states
    const std::array<double, TOTAL_BONDS>& occupations() const { return b_; }
    double occupation(int n) const { return b_[n - 1]; }
    double total_occupation() const {
        return std::accumulate(b_.begin(), b_.end(), 0.0);

B* ≈ 36.2 bonds at 300K
