226- In a moving car, which diagram best shows the reaction rate situation, indicating the equilibrium production rate of $\text{NO(g)}$ in the first moment of burning gasoline inside the cylinder?
[Figure: Four pairs of diagrams (1)--(4), each showing two circular gauges labeled M (middle), S (left), F (right) with arrows indicating ``reverse'' (برگشت) and ``forward'' (رفت) rates:
(1) Both gauges: reverse arrow pointing left-down, forward arrow pointing right; rates appear equal and moderate.
(2) Both gauges: reverse arrow pointing left, forward arrow pointing right; forward rate higher than reverse.
(3) Both gauges: reverse arrow pointing left, forward arrow pointing up; forward rate higher.
(4) Both gauges: reverse arrow pointing up, forward arrow pointing up; rates appear equal and high.]
