← ScienceWhich consequence results when a reaction's rate constant declines under constant temperature?
A)Decreased activation energy requirement
B)Diminished equilibrium constant value✓
C)Temperature change is thermodynamically induced
D)Increased concentration of product species
💡 Explanation
A reduction in a rate constant decreases reaction speed because a lower rate translates to slower formation of products, hindering attainment of equilibrium; therefore, diminishing the K value directly, rather than raising catalytic speed or overcoming kinetic energy barriers.
